Explanation:
Simple sentences contain a single independent clause with no dependent clause and state a simple statement. So, sentences 5 and 6 are simple sentences.
Compound sentences are those sentences that contain two or more independent clauses. And these clauses are joined by coordinating conjunctions "for, and, nor, but, or, yet, so" (FANBOYS). Sentences 1 and 4 are compound sentences.
Complex sentences are those sentences that contain an independent clause and a dependent clause. These two clauses are joined by subordinating conjunctions. So, sentences 2 and 3 are complex sentences.
