Answer: B the police officers arrested the suspected and put it in jail.
Explanation: Pronoun is a word that takes place of noun or/and refers to a noun. Pronoun antecedent agreement occurs when the pronoun agrees in number (singular or plural) and person (first, second or third) with its antecedent. For example:
In A: "Dave and I like Sundays because WE can watch football" is correct, because the pronoun "we" is referring to the compund subject Dave and I.
The alternative C is incorrect because the pronoun IT is not appropriately attributed to "the suspected". The correct pronoun would be he or she.
