Take another look at the sentence:

Because Kerri Ann __________ all of her biology homework, she spent the rest of the evening with her friends. The next morning, when Dr. Wright passed out the difficult pop quiz, Kerri Ann realized that her books should have been her only company.

The sentence requires a past tense form of do, an irregular verb. Had done, one of the choices, correctly combines the past participle with the auxiliary verb had.

Verb Simple Present Simple Past Past Participle
do do(es) did done (with had)

Done, by itself, is incorrect because it requires an auxiliary verb. Before you continue, review the rules for irregular verbs.
