Select the option in which the numbers share the same relationship in set as that shared by the numbers in the given 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)

(39, 78, 81)

(42, 84, 87)

(84, 168, 171)

(39, 78, 81)

(42, 84, 87)

The logic followed here is :

(39) × 2 = 78 and  78 + 3 = 81

as

(42) × 2 = 84 and 84+ 3 = 87

Same as (84, 168, 171)

(84) × 2 = 168 and 168+ 3 = 171
