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 /deleting /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)

(4, 5, 20)
(7, 8, 56)

(7, 12, 84)

(4, 5, 20)
(7, 8, 56)

The logic followed here is :

(second number × Ist number) = IIIrd number

as

(5 × 4) = 20

(8 × 7) = 56

Therefore (7, 12, 84)

(12 × 7) = 84
