Find the ODD one out from the given options.

Correct option is A

1. (a) GEC
· Pattern: Each letter decreases by 2 (7 - 5 = 2, 5 - 3 = 2)
2. (b) NKH
· Pattern: Each letter decreases by 3 (14 - 11 = 3, 11 - 8 = 3)
3. (c) GDA
· Pattern: Each letter decreases by 3 (7 - 4 = 3, 4 - 1 = 3)
4. (d) ZWT
· Pattern: Each letter decreases by 3 (26 - 23 = 3, 23 - 20 = 3)
Conclusion:
In options (b), (c), and (d), the letters decrease by 3 each time, whereas in (a), the letters decrease by 2 each time.
Thus, the odd one out is: (a) GEC
