Correct option is A
Given: ZY, XW, UT, (…) , LK
Logic: the letter are shifted -2, -3, -4, -5..
First Letters: Z, X, U, ( ? ), L
Z → X (shifted by -2)
X → U (shifted by -3)
U → Q (shifted by -4)
Q → L (shifted by -5)
Missing first letter: Q
Second Letters: Y, W, T, ( ? ), K
Y → W (shifted by -2)
W → T (shifted by -3)
T → P (shifted by -4)
P → K (shifted by -5)
Missing second letter: P
So, the missing group is QP
