I think we can agree that:
(48÷2)(9+3) = 288.
and:
48÷(2(9+3)) = 2.
If those two answers are accepted by all, then by applying the order of operations rule, specifically the do multiplicdation/division from left to right, it can be inferred that:
48÷2(9+3) = (48÷2)(9+3)
Thus the correct answer is 288.
