If in a code language CRACKS is written as DQBBLR, then how would SPROUT be written in that same code language?

Correct option is B

Given - CRACKS is written as DQBBLR, then how would SPROUT

Logic - letters are + 1, -1 alternatively.

first

C + 1 = D
R - 1 = Q
A + 1 = B
C - 1 = B
K + 1 = L
S - 1 = R
So, CRACKS is written as DQBBLR.
Similarly,  
S + 1 = T

P - 1 = O
R + 1 = S
O - 1 = N
U + 1 = V
T - 1 = S
So, SPROUT is written as TOSNVS.
Answer: (B) TOSNVS
