Select the set in which the numbers are related in the same way as are the numbers of 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)

(11, 10, 21)

(14, 6, 160)

(19, 12, 217)

(11, 10, 21)

(14, 6, 160)

The logic followed here is :

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

as

11² - 10 ² = 21

14² - 6² = 160

Same as (19, 12, 217)

19² - 12² = 217
