Answer: Complex
Explanation:
A simple sentence is a sentence that contains a subject and verb and expresses a complete thought. For example, I like tea
A compound sentence is a sentence that contains at least two independent clauses. These clauses are joined by a semi-colon or a conjunction [and, but, or etc.] . Every of these clauses can form a sentence by itself. For example, I dislike tea but John likes tea
A complex sentence is a sentence that contains an independent clause & a subordinate clause. While the independent clause expresses a complete thought, the subordinate clause does not. For example, I missed dinner because I was late
A compound-complex sentence is a sentence that contains at least two independent clauses & at least one subordinate clause. For example, I didn't come because I was ill so Jack was not happy
