Question

What kind of complement is the underlined word? The speaker sounded hoarse after talking for a few hours. (HOARSE underline)

Answer 1

Your answer is B, because it's describing the type of voice, which is the job of an adjective.

Answer 2

The answer is letter B-- predicate adjective. 

A predicative adjective could be one adjective or a phrase which includes an adjective and other modifiers. In the given sentence above, hoarse acts as a predicate adjective. 

A predicate nominative, on the other hand, is a noun or a pronoun that always follows the verb and renames or describes the subject. 

Direct object and indirect object are far from the correct answer.
