"We played for hours" is a complete sentence.

Answer: B

Explanation

It is a sentence because it has at least one subject clause and a predicate.

In the above sentence, the subject is we and the predicate is played.

A subject is anything in the sentences such as a person or object doing the action.

The predicate describes the subject's actions.

This is a basic sentence and the requirement is that it should have subject and predicate.

In addition, a complete sentence has a clear meaning that doesn't leave the reader having any lingering questions regarding the conveyed message.
