Take another look at the sentence:

On Christmas Eve, Captain Beane wore a pair of antlers while greeting passengers boarding his 727. The costume __________ little trust in Louise, whose fear of flying required a serious pilot.

The sentence requires the past tense of build, an irregular verb. Built is the simple past form.

Verb Simple Present Simple Past Past Participle
build build(s) built built

Builded, the form you chose, is a spelling error. Before you continue, review the rules for irregular verbs.
