c) it is a subject-linking verb-predicate noun.

Explanation:

a) It is not just a subject-verb. That would exemplified in the following sentence: "The dog barks."

b) It isn't a subject-verb-direct object since it has a linking verb: is

d) It isn't a subject-linking verb-predicate adjective since an adjective describes what kind, which one, and how many. A thesaraus is a type of noun.

e) A subject-verb-indirect object-direct object would be incorrect since we have a linking verb not just a verb. An indierect object is what the direct object is talking about. An example of this would be The boy pumped his tires. The tires is what the boy is pumped. There is no linking verb becase pumped is an action verb.

Thus, we can conclude that the answer is c) subject-linking verb-predicate noun.
