Correct Answer:
Option B —
Both A and R are true but R is not the correct explanation of A
Here is the step-by-step logical breakdown:
1. Evaluating the Assertion (A)
Statement: "No cat is a dog."
Is it true? Yes. Cats and dogs are completely different species. No animal can be both a cat and a dog at the same time.
2. Evaluating the Reason (R)
Statement: "Some dogs are pets."
Is it true? Yes. Many dogs are kept as pets, while others might be wild or working animals.
3. Evaluating the Explanation
To see if R explains A, we ask: Does the fact that some dogs are pets cause or prove that no cat is a dog?
No, it does not. The two statements are talking about entirely different relationships. One is about the boundary between cats and dogs, and the other is about dogs being pets. Cats and dogs would still be separate species even if no dogs were pets.
Therefore, while both statements are completely true on their own, the Reason has nothing to do with the Assertion and is not the correct explanation for it.
Correct Answer: B) Both A and R are true but R is not the correct explanation of A
