Solution

A simple sentence has only one independent clause, which means it expresses a complete thought by itself. This sentence has more than one independent clause. A complex sentence has one independent clause and one or more dependent clauses. While there are multiple clauses in this sentence, they are all independent clauses and can stand alone as complete sentences. A compound sentence has two or more independent clauses joined by a coordinating conjunction like "and," "but," "or," "so," "yet," or "for." This sentence clearly uses "and" to join two independent clauses: "He went to Madras" and "He got his visa and come back." Therefore, because the sentence has two independent clauses joined by a coordinating conjunction, it is classified as a compound sentence.
