The correct option is D None of the above
A subject complement is an adjective, a noun or any phrase that follows a
linking verb and gives more information about the subject.
In the given sentence, "the" is an article, "thief" is a noun that performs as the subject and "ran" is the verb. None of these perform as the subject complement, hence options A, B and C are incorrect. Because this sentence does not have a subject complement, option D is correct.
