Answer:
Objective, ambiguous is the correct answer.
Explanation:
An objective pronoun refers to the object of the verb, meaning that it is affected by the action in the sentence (in this case choreographed). We can also identify an object because it is after the verb in the sentence, such as them. It is also ambiguous; this happens when the pronoun has more than one antecedent, in the sentence "trainer" and "routine" could also be substituted by them.
