Fill in the blank with the most appropriate word. She asked him where ___________.

The correct answer is: B. the party was

The sentence is in the past tense, so the verb “to be” must be conjugated in the past tense as well. The past tense of “to be” is “was”.

The other options are incorrect because they are not in the past tense.

• A. is the party is in the present tense.
• C. was the party is in the past tense, but it is not the correct form of the verb “to be”.
• D. is party is not a grammatically correct sentence.
