Correct option is C

Logic: Sum of squares of all side number = Middle number
For, 1st figure
52 = 25, 72= 49, 32= 9, 42= 16
25 + 49 + 9 + 16 = 99
For, 3rd figure
32= 9, 92= 81, 52= 25, 72= 49
9 + 81 + 25 + 49 = 164
For, 2nd figure
72= 49, 62= 36, 22= 4, 52= 25
49 + 36 + 4 + 25 = 114
The missing number is 114.
Thus, correct option is (c).
