The correct answer is B. A simple sentence expresses one complete thought; it's composed of an independent clause that follows the subject-verb pattern.
Explanation
A simple sentence is a syntactic unit that expresses a complete idea, which means it is an idependent clause. The sentence has a basic structure that is composed of a subject, verb (action), and complement. Simple sentences are independent clauses because their meaning does not depend on any complement that contextualizes them. An example of a simple sentence is "I play in the park with my friends". In this sentence the subject is "I", the verb is "game" and the complement is "in the park with my friends". According to the above, the correct answer is B.
