Question

Ranjit: _____ you please tell me whose bag is that?

• A. must
• B. will
• C. would
• D. could

Answer 1

The correct option is D could

Option D is the correct answer because 'could' is used to make polite requests.

'would ' is also used to make polite requests but the difference between the two is-

could = possibility + ability
would = definiteness + desire

The above two equations make it clear that 'could' should be used over 'would' because a request is being made, and getting an answer is not necessary.

Option A is incorrect because 'must' is used when something needs to be done inevitably.

Option B is incorrect because 'will' is used in the future tense.
