Select the set in which the numbers are related in the same way as are the numbers of the following set.

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 - Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

(63, 81, 7)

(84, 49, 12)

(99, 121, 9)

(63, 81, 7)

(84, 49, 12)

The logic followed here is :

(First number ÷ Third number)² = Second number

As

(63 ÷ 7)² = 81

(84 ÷ 12)² = 49

same as in option (99, 121, 9)

(99 ÷ 9)² =121
