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.)
(3, 6, 18) (5, 7, 35)

In each set, the product of the first and second numbers will form the third number.

(3, 6, 18)

third number = $$3\times6$$ = 18

(5, 7, 35)

third number = $$5\times7$$ = 35

Option (a) (8, 13, 94)

third number = $$8\times13$$ = 104

The above given logic is not satisfied here. So this is not the correct answer.

Option (b) (7, 12, 74)

third number = $$7\times12$$ = 84

The above given logic is not satisfied here. So this is not the correct answer.

Option (c) (8, 12, 86)

third number = $$8\times12$$ = 96

The above given logic is not satisfied here. So this is not the correct answer.

Option (d) (6, 14, 84)

third number = $$6\times14$$ = 84

The above given logic is satisfied here. So this is the correct answer.
