A compound sentence needs at least two independent clauses and can be combined by conjunctions such as and, or, but, for, yet, nor and so. The independent clauses can also be combined by a semicolon ;
(A) If we look at A, we can see A does not have two independent clauses. There is a depend and an independent clause and that is why we have a comma after go in A.
(B) What I said about A is the same for B
(C) Ah! good old C. C has two independent clauses and has the conjunction and after mall and before John. This is very important because this is where one independent clause stops and another independent clause starts. C has everything that makes up a compound sentence so the answer is C.
(D) If we look at D, we can see D is just a single independent clause, which is asking a question. Thank you for using Brainly.com
