In the following question, select the related letters from the given alternatives.
OTYJ: QVAL :: DGKX: ?

Correct option is A

Given:

Each letter in OTYJ is shifted by a certain number of positions in the alphabet to get QVAL:
O to Q: +2
T to V: +2
Y to A: +2 (after reaching Z, it wraps around to A)
J to L: +2
Thus, each letter in the first group is increased by 2 to get the corresponding letter in the second group.
Now, applying the same pattern to DGKX:
D to F: +2
G to I: +2
K to M: +2
X to Z: +2
So, DGKX becomes FIMZ when each letter is shifted by +2.
The correct answer is (a) FIMZ.
