Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number.

25:49::42:36::74:? ​​

Logic: (Sum of digits of 1st number)²= 2nd number

The First Pair:

2 + 5 = 7 ,  7² = 49

and the second pair:

42 : 36

4 + 2 = 6 ,  6² = 36

then, the same pattern follow:

74 : ?

7 + 4 = 11,

11² = 121

Thus, the  correct answer is 121
