a.after
b.before

The correct answer is A. After

Explanation:

In grammar, a complement refers to a word or set of words that provide information or describe the predicate of a sentence, that includes the verb, direct object. In the case of objective complement, these type of complement describes the direct object of a sentence, which is the object that is related to the action and answer to the question "what?" or "whom". Because of this, it is common the objective complement is placed right after the direct object in order to describe it or rename it. For example, in the case of the sentence "Jane considers Joe brave" the direct object is "Joe" and the objective complement is "Brave" which describes or renames the direct object and is placed after it. From this, it can be concluded the objective complement comes "after" the direct object.
