What kind of complement is the underlined word? Did she loan Larry her box of markers? A. indirect object B. predicate nominative C. direct object D. predicate adjective (Larry is underlined).

Larry is indirect object, the correct answer is A. If there are two kinds of objects in a single sentence, the rule is that the indirect object goes first, and is followed by a direct object. Here, the direct object is her box of markers, which makes Larry indirect object.

Predicate nominative and adjective follow a linking verb, and since there are no linking verbs in this sentence, those two options cannot be correct.
