Explanation - YUVA is a part of India@75 Project (Azadi Ka Amrit Mahotsav) to bring to the fore the perspectives of the young generation of writers on themes like Unsung Heroes, Freedom Fighters, Unknown and Forgotten Places and their role in National Movement, and other related themes in an innovative and creative manner. This scheme will thus help to develop a stream of writers who can write on a spectrum of subjects to promote Indian heritage, culture and knowledge system. The National Book Trust of India India under the Ministry of Education as the Implementing Agency will ensure phase-wise execution of the Scheme under well-defined stages of mentorship. The results of the Prime Minister’s Scheme for Mentoring Young Authors (PM-YUVA 3.0) have been declared, with 43 young authors selected through an All-India contest. The Prime Minister’s Scheme for Mentoring Young Authors (PM-YUVA 3.0) aims to nurture young writers under 30 years of age, providing them with mentorship and exposure to hone their creative writing skills. (The prompt answer says C, which implies Statement 2 is incorrect or the provided answer key has an error relative to the text. However, the text explicitly says "National Book Trust of India... as the Implementing Agency". Standard knowledge confirms NBT under Ministry of Education implements it. But if the key says C, perhaps there is a nuance about 'Ministry of Education' vs 'Ministry of Culture' in a specific context or a trick. Re-reading carefully: the provided text says "National Book Trust of India under the Ministry of Education as the Implementing Agency". So Statement 2 is correct according to the text. Statement 1 is correct. Statement 3 is correct. Thus, D should be the answer based on the text provided. However, the provided answer key is C. Often such discrepancies in "Answer - C" vs "All of the above" are due to errors in the source material's key. Based strictly on the provided text, all statements are supported.) Correction Note based on provided text and standard logic: The text supports all three statements. If the provided answer key is C (1 and 3 only), it contradicts the text which says NBT under Ministry of Education implements it. I will follow the provided text's content which supports all.

Explanation - Frequency Comb is a special kind of laser light whose spectrum, or set of frequencies, resembles the teeth of a comb. Frequency combs are simple and compact tools that phase coherently connect the radio frequency domain (say below 100GHz) with the optical domain (say above 200THz) (Statement 2 is correct). Characteristics of Frequency Comb — Instead of containing just one colour (one frequency) (Statement 3 is incorrect), it emits a large number of evenly spaced frequencies (not unevenly spaced, so Statement 1 is incorrect). The spacing is extremely regular. Frequency combs are widely-used, high-precision tools for measuring and detecting different frequencies colours — of light. It has high stability and precision. Applications of Frequency comb — It helps scientists compare an unknown light frequency to a stable reference with extraordinary precision. It is an important modern tool to calibrate atomic clocks and measure shifts in light caused by gravity. It is used to detect exoplanets (Statement 4 is correct). It is also used in high-speed spectroscopy. 

Explanation - Industrial hemp (Cannabis sativa L.) is botanically related to marijuana, but with very different properties. While marijuana is rich with tetrahydrocannabinol (THC), the psychoactive component that makes pot a drug of choice by many, hemp contains only the smallest traces of THC (<0.3%) (Statement 2 is incorrect as it has low THC, not high). It is an herbaceous, dioecious plant belonging to the Cannabis genus within the Cannabaceae family (Statement 1 is correct). It is high in fiber and low in active tetrahydrocannabinol (THC). Applications of Industrial Hemp — It is used for varieties used for recreational, therapeutic, and industrial purposes, commonly referred to as marijuana and hemp, respectively. Its stalk can be used to produce biofuel, auto parts, paper, upholstery, and fiber for cloth and other textile items. Its stem can also be processed into building materials, industrial products and different kinds of papers. Its seeds can be used to produce feed or food or the sources of oil that can be converted into a lotion or cosmetic products (Statement 3 is correct).
