Which word in the sentence, if any, should be followed by a semicolon?

My parents are cleaning the house that means we must be expecting company.

A. cleaning

B. house

C. There is no error in semicolon usage.

D. must

The word in this sentence which should be followed by a semicolon is b) house.

My parents are cleaning the house; that means we must be expecting company.

A semicolon separates two related independent clauses. There are two independent clauses in the sentence: "My parents are cleaning the house today" and "that means we must be expecting company." This means there should be a semicolon in the sentence. It would go after the word "house," because that is where the first clause and the second begins. Therefore, the answer is D. house.
