Explanation:
A complex sentence is a sentence that has one independent clause and at least one dependent clause. An independent clause is a full sentence but a dependent clause needs an independent clause to be taken as a full sentence. Also, in a complex sentence, the dependent clause has to start with a subordinating conjunction.
