Answer:
I believe the answers are:
I've applied to three universities----> It deserves how many times it happened
I've seen this film before----> It happened at an unspecified time in the past
Explanation:
The word 'three' is explaining to us that she/he had applied many times.
'Seen before' tells us that it happened in the past but it does not give us a specific time, day or date in the sentence.
The correct answer for the given statement above would be option A. She will have been. The pronoun "she" is in the singular, third person. Other pronouns that are singular, third person include he, and it. And "will have been" is the conjugation of the verb "to be" in the future perfect tense.
