Answer:
C. present
Step-by-step explanation:
Although we do not know which section of the sentence is in italics, for the question to make sense, it would have to refer to the verb. A verb is a word that describes an action. In this example, the verb is "is describing." This is an action that is taking place as the same time as the speaker is describing it. Therefore, it is a present. More specifically, this is an example of a present progressive or continuous.
