Correct option is A
Following the logic here is: Number in the bottom left = (Product of two right side numbers ) + ( Number in the top left ).

30 = ( 9 3 ) + 3
30 = 27 + 3
30 = 30

50 = ( 6 × 8 ) +2
50= 48 +2
50 = 50
Similarly,

? = (5 × 6 ) + 7
? = 30 + 7 = 37
37 =37
Thus the correct answer is:Option A
