Correct option is D
Given: XY: WW :: JM: ?
Logic: 1st letter -1 and 2nd letter – 2.
XY: WW
For the first letter, X, move back 1 position in the alphabet:
X → W
For the second letter, Y, move back 2 positions:
Y → W
Thus, XY → WW.
Apply the same logic to JM:
JM: ?
For the first letter, J, move back 1 position:
J → I
For the second letter, M, move back 2 positions:
M → K
So, JM → IK.
Correct answer: (d) IK
