The correct Answer is:
To analyze the given statements, we need to break down the assertion (A) and reason (R) provided in the question. ### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that "DNA contains all the necessary information and instructions for cell reproduction." - This statement is true because DNA (deoxyribonucleic acid) carries the genetic information essential for the growth, development, and reproduction of living organisms. It provides the instructions for synthesizing proteins, which are crucial for cellular functions, including reproduction. 2. **Understanding the Reason (R)**: - The reason states that "Reproduction is not essential for living organisms." - This statement is somewhat misleading. While it is true that individual organisms do not need to reproduce to survive (as they can live their life cycle without reproducing), reproduction is essential for the continuation of a species. Therefore, while reproduction is not necessary for the survival of an individual organism, it is essential for the survival of the species as a whole. 3. **Evaluating the Relationship Between A and R**: - The assertion (A) is true, and the reason (R) is also true. However, R does not correctly explain A. The assertion is about the role of DNA in reproduction, while the reason discusses the necessity of reproduction for living organisms, which is a different aspect. - Thus, we conclude that both statements are correct, but R is not the correct explanation for A. 4. **Final Conclusion**: - The correct answer is that both A and R are true, but R is not the correct explanation of A.
