Explanation:

The direct object in a sentence is the thing or person being acted upon, the receiver of the action described by the verb. It usually answers the questions "Who?" or "What?". In the particular sentence we are analyzing here, we also have an indirect object. It answers questions such as "To whom?" or "For what?". Let's study the sentence:

-  Dad bought Terri a special lightbulb for her bedroom lamp.

--> Dad bought what? A special lightbulb. Therefore, "a special lightbulb" is the complete direct object of the sentence. Since the question asks us to find the noun in the direct object, we should answer "lightbulb".

Note: Dad bought a lightbulb to whom? Terri. Terri is the indirect object.
