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)

(15, 9, 4)

(7, 2, 3)

(19, 13, 4)

(15, 9, 4)

(7, 2, 3)

The logic followed here is :

(Ist term  - second term)  = X  then ( X - 2 )=  third term

15 - 9 = 6 then  6 - 2 = 4

7 - 2 = 5 then  5 - 2 = 3

Similarly in option 2

19 - 13 = 6 then 6 - 2 = 4
