Also Ms.Sue already answered the question.

To determine the answer to this question, we need to analyze the sentence structure.

A compound sentence is formed by joining two independent clauses with a coordinating conjunction (such as "and," "but," or "or").

A simple sentence contains one independent clause, expressing a complete thought.

A complex sentence consists of one independent clause and at least one dependent clause, which cannot stand alone as a complete sentence.

A compound-complex sentence includes multiple independent clauses and at least one dependent clause.

Now, let's examine the given sentence: "The senior class took a trip to Washington, D.C. and Annapolis for their research project."

In this sentence, we have one subject ("senior class") and one main verb ("took"). The phrase "to Washington, D.C. and Annapolis" functions as a prepositional phrase modifying the verb "took." The phrase "for their research project" also functions as a prepositional phrase, providing additional information about the purpose of the trip.

Since the sentence contains only one subject and one verb, without any conjunctions or dependent clauses, we can conclude that it is a simple sentence (option B).

Is Ms. Sue, and writeacher real teachers? Might be getting wrong answers.

Yes, compound.
