Question

Which answer is a correctly punctuated compound sentence?








A.
This music is very different and I don't know if I like it.







B.
This music is very different I don't know if I like it.







C.
This music is very different, I don't know if I like it.







D.
This music is very different; I don't know if I like it.

Answer 1

I believe A is incorrect because there should be a comma before the and
B is incorrect because it's basically run-on sentence.
D is preferable over C because the semicolon is used to connect two independent clauses which it does in this case.
