The correct Answer is:
To analyze the given statements and determine their truthfulness, we will break down the assertion (A) and reason (R) step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that "DNase can inhibit the process of transformation." - DNase is an enzyme that digests DNA. If DNA is digested, it cannot be taken up by bacteria. 2. **Understanding the Reason (R)**: - The reason states that "Transformation is the absorption of DNA segment from the surrounding medium by a living bacterium." - This statement describes the process of transformation accurately. Transformation involves bacteria taking up free DNA from their environment. 3. **Evaluating the Relationship**: - The assertion (A) is true because if DNase is present, it will break down the DNA into smaller components, preventing the bacteria from absorbing intact DNA. - The reason (R) is also true as it correctly defines the process of transformation. 4. **Conclusion**: - Since both the assertion and the reason are true, and the reason correctly explains why the assertion is true, we conclude that both statements are valid. Therefore, the correct answer is that both A and R are true, and R is the correct explanation for A. ### Final Answer: Both the assertion (A) and the reason (R) are true, and R is the correct explanation for A. ---
