OA should be C.
1. Not sufficient. Tells only the no. of cameras sold yesterday. Not useful to determine the cameras sold today.
2. Not suff. Tells only the profit in excess of yesterday as 48 dollars. 48 being a multiple of both 12 and 16, cant tell what excactly the no. of cameras sold.

Combining both, We know that yesterday 10 cameras sold. So today, according to 48 dollar profit, 3 more cameras sold. i.e., 13 cameras sold today.

So, C should be the answer.
