Answer: D) possessive; adjective.
Explanation: a pronoun is a word that can function as a noun phrase used by itself and that refers either to the participants in the discourse or to someone or something mentioned elsewhere in the discourse. Possessive pronouns are the ones that show belonging. In the given sentence we can see an example of a pronoun in the possessive case (our) that is acting as an adjective, because it is modifying the noun "turn."
