Question

Which of the following examples would be classified as a dependent clause?

Answer 1

it aint A  ......................................................

Answer 2

I believe there is more than one answer to this question. 
B is the only answer that is an independent clause. A, C, and D are all dependent clauses, so presumably they are all answers. 
They are dependent because they cannot stand alone as a sentence without an independent clause. 
Hope that helped you.
