Which sentence is in the subjunctive mood? where were you yesterday? i’m glad you came to the party yesterday. i’d hoped you’d be able to attend the party. i wanted to see you yesterday.

I’d hoped you’d be able to attend the party.

The correct answer is B. I'd hoped you'd be able to attend the party.

Explanation:

The main function of the subjunctive mood is to express hypothetical situations such as desires or hopes as these are only a possibility but not a reality. The sentence "I'd hoped you'd be able to attend the party" belongs to this mood because it expresses only a wish, hope or desire through the verb "hope"; also, the use of the past perfect in "I'd hope" suggests the person could not attend the party after all and therefore, the speaker is referring to an unreal situation.
