Which of these statements reflects subjunctive mood?
i wish it were possible to go to the movie tomorrow.
if we go to a movie, will i be able to have popcorn?
she hoped to go to the movie and have popcorn.
he couldn't go to the movie without his wallet.

Subjunctive is a wishful thinking, like "i wish Elmo was real". Since only one of them are wishful thinking, the answer is A. Clue words: wish

A.  I wish it were possible to go to the movie tomorrow.

The subjunctive mood is when the action is contrary to fact or does not exist.  This is frequently indicated with the appearance of the words “if” and “wish.”  When the words “if” and “wish” appear, the verb “was” should always be in the plural form regardless of whether the subject is singular or plural.  For instance, you would typically pair “I” with “was” because “I” is singular.  However, when “if/wish” appear, “was” will need to be plural as in the following:

CORRECT: I wish I were taller.  

INCORRECT: I wish I was taller.

CORRECT: If she were there.

INCORRECT: If she was there.  

c. is the answer to your question.
