I searched it up I got this I personally think its D but, not sure Hope this helped!
I think it is e because A dependent clause is a group of words with a subject and a verb. It does not express a complete thought so it is not a sentence and can't stand alone.
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.
