Take another look at the sentence:

Because her hands were still slippery from the dishwater, Marilyn dropped the watermelon, which __________ on the floor in an explosion of pulp and seeds.

The sentence requires the past tense of burst, an irregular verb which always has the same form. Burst, then, is the simple past form.

Verb Simple Present Simple Past Past Participle
burst burst(s) burst burst

Busted, the choice you made, is slang. Although people do use busted, you should avoid it, especially in formal situations. Before you continue, review the rules for irregular verbs.
