Concept:Respond using the same auxiliary verb as the polite request.
Explanation:This sentence tests the correct reply to a request using “Would you mind…?”
When you do not mind doing something, you answer “No” to confirm willingness.
The matching short response uses “would,” so say: “No, I wouldn’t (mind).”
Option A and D use “do/don’t,” which do not match the auxiliary “would.”
Option C mixes “Yes” with “wouldn’t,” which is contradictory.
Thus, the only logical and grammatically consistent choice is B.
Answer:B. No, I wouldn’t.
