Answer:
The answer is B.
Step-by-step explanation:
Pronouns are part of speech whose function is to replace nouns. Therefore antecedent is a noun that was replaced by a pronoun.
For example, I love chocolate because it makes me happy.
In this example, we use the pronoun it to avoid repeating the noun chocolate.
In this question the object labelled old and in a need of a lot of work was the house.
