Answer: A) Simple.
Explanation: a simple sentence is one with a subject and a predicate. A compound sentence has more than one subject or predicate (two or more independent clauses). A complex sentence has at least one subordinate (dependent) clause. A compound-complex sentence is one that has at least two indepenent clauses and one dependent clause. A fragment is a phrase that is lacking a subject or a predicate. The given sentence has only one subject (she) and a predicate, so it is a simple sentence.
