Answer & explanation
Correct answer: option 3
THE LOGIC;
1) IDWHU,
I → (-5) → D → (-7) → W → (+11) → H → (+13) → U
2) UPITG,
U → (-5) → P → (-7) → I → (+11) → T → (+13) → G
3) EZSFV,
E → (-5) → Z → (-7) → S → (+11) → D not F → (+13) → Q not V
4) CXQBO,
C → (-5) → X → (-7) → Q → (+11) → B → (+13) → O
Thus, EZSFV is the odd one.
