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

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its 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)

(76, 75, 1)

(90, 87, 9)

(56, 48, 64)

(76, 75, 1)

(90, 87, 9)

The logic followed here is :

(Ist number) - second number)² =  IIIrd number           

As

(76 - 75)²   = 1

(90 -87)² =  9

same as (56, 48, 64)

(56 - 48) = 64
