The correct answer is A. Compound
Explanation:
According to grammar, a compound sentence is one that includes two or more independent clauses, which are sets of words with a subject, verb, and that express a complete idea. Besides this, a compound sentence can be identified because it is common coordinating conjunctions such as but, or, and, yet or so are used to link the clauses. The sentence "Mike wanted to go to the pool, but Jess wanted to go to the mall" is an example of this type of sentence, this can be explained as this sentence includes the coordinating conjunction "but", and also integrates to independent clauses "Mike wanted to go to the pool" and "Jess wanted to go to the mall" as each of this is a complete sentence by itself.
