Taking Stmt (1) alone,
r < 4 can have Prime numbers infinite, ( considering -ve int also )
Taking Stmt(2) alone, No Clue for "r"

Taking Both (1) and (2),
q=18, and r < 4, q = 2x3x3. clue is it asks if "q is a multiple of r" and Not the value of "r".

Hence Both Stmt are sufficient to ans.

Had the question being "If q is a multiple of prime numbers, what is value of r? "...my ans would be NONE OF THE STMTS.

In my opinion, the answer is E.

The question does not say that r is an integer. So r could be 3/7 or r could be -500.

So both (1) and (2) are insufficient.
