Question

3.

Which sentence is a complex sentence?
A. The school has a new science lab and a new auditorium.
B. The school is building a new auditorium as the science lab is already finished.
C. The school has a new science lab, and plans for a new auditorium are moving ahead.

Answer 1

I believe it's C. The school has a new science lab, and plans for a new auditorium are moving ahead.

Step-by-step explanation:

a complex sentence must have two or more coordinate independent clauses and one or more dependent clause. In this case, the independent clause is "the school has a new science lab", because this alone can be a sentence. The dependent clause here is "plans for a new auditorium are moving ahead", since this phrase alone cannot make a complete sentence. hope this helps!
