B. as an object complement
C.as an indirect object
D. as a predicate nomintive

Answer 1

NovaNet: D. a predicate nominative

Answer 2

The word reality functions as D. a predicate nominative in the sentence.
A predicate nominative is the first noun found after a linking verb (which connects two parts of a sentence). In this case, the linking verb is became, and the first (and the only) noun after that verb is reality, thus making it a predicate nominative rather than a predicate adjective (which would obviously require an adjective).
