Answer:
Simple sentence
Explanation:
A simple sentence contains a subject and a verb. It expresses a single complete thought that can stand on its own.
A compound sentence has two independent clauses. An independent clause is a part of a sentence that can stand alone because it contains a subject and a verb and expresses a complete thought. Basically, a compound contains two simple sentences. These independent clauses are joined by a conjunction.
Here "and" is used but not as a conjunction so it is a simple sentence.
