I got C as S1 & S2 both alone are insufficient but together sufficient.

Statement (1) alone:
a+3a = b+3b-4
4a = 4b-4
a = b-1
a-b = -1
Does statement (1) alone give us enough information to find a-b? Yes. AD.
Statement (2) alone (it's not clear whether "two times more than" means 2x what follows or 3x what follows, but it doesn't change the verdict):
a+3b = 3b+9a
a = 8a
a = 0
Does statement (2) alone give us enough information to find a-b? No. A.
Answer choice A.
