Answer:
A. I love cheese!
Step-by-step explanation:
Simple sentences contain one independent clause, which consists of a subject and a verb, and expresses a complete thought. In this case, the subject is the subject pronoun I, the verb is love, and cheese works as a complement or direct object.
The rest of the alternatives are incorrect because options B and C are complex sentences with one independent clause and one subordinate clause; while option D is a compound sentence with two independent clauses.
