Mi familiagrande,
son
eres
es
sois

C. es

Explanation:

Mi familia es grande. "Es" would be the correct conjugation of ser. It is correct for two reasons, because it is in the present tense, like your family, and it is singular. While it first it may seem like it should be plural because there are multiple people in your family since it is only one group it should be singular.
