The correct answer would be, "Carl wished it was last year at this time so he could invite someone else to homecoming and have a good time."
the former would be the correct answer.
The correct option is B, which uses 'were' in the subjunctive mood to express a wish that is contrary to fact. Sentence A incorrectly uses 'was', which is not suitable for this context. Therefore, the correct sentence is, 'Carl wished it were last year at this time so he could invite someone else to homecoming and have a good time.'
