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 /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.)
(11, 8, 57)
(13, 4, 51)

Sum of first and second number of sets is multiplied by 3 to get third number of set.

(11, 8, 57)

(11+8)×3 = 19×3=57

and

(13, 4, 51)

(13+4)×3 = 17×3=51

Therefore,
