Which sentence is a compound sentence?

• A. I like pizza.
• B. I like pizza, and my brother likes pasta.
• C. Because I was tired, I slept.
• D. The dog slept alone.

Answer: (B)

A sentence with two independent clauses joined by a coordinating conjunction forms a compound sentence. Here, “I like pizza” and “my brother likes pasta” are both complete thoughts that could stand alone, and they’re connected by “and,” which creates one sentence of the compound type. The other options either present a single complete thought (a simple sentence) or begin with a dependent clause like “Because I was tired,” which makes it a complex sentence rather than compound.
