Topic: Subject Verb Agreement,

Best Answer Explained in Below-:

In the sentence "Rahim, and not you --—--- won the prize," we need to choose the correct auxiliary verb to fit with the subject and maintain grammatical consistency. The phrase focuses on Rahim as the person who won the prize.

The option 'has' (B) is the correct choice because it indicates a completed action in the present perfect tense. The structure "has won" implies that Rahim's victory is relevant to the present situation, perhaps suggesting that the prize is still being discussed or that its significance continues.

On the other hand, 'is' (A) would imply a current state, which does not fit because it would be more appropriate if we were describing an ongoing situation rather than a completed action. 'Was' (C) refers to a past action that has no relevance to the current context, and 'are' (D) cannot be used here because 'won' is a singular past action and does not match the plural form.

Thus, 'has' effectively communicates the intended meaning and aligns with the context of the completed action, making it the grammatically and contextually appropriate choice.
