Find the ODD one out from the given options.

Correct option is A

To find the odd one out, let's analyze each option to see if there is a pattern or relationship among the letters.
Step-by-Step Analysis:
TRT:
The first and last letters are the same, T.
The middle letter R is two letters after T in the alphabet (T → R is -2 in alphabetical order).

BDB:
The first and last letters are the same, B.
The middle letter D is two letters after B in the alphabet (B → D is +2 in alphabetical order).

QSQ:
The first and last letters are the same, Q.
The middle letter S is two letters after Q in the alphabet (Q → S is +2 in alphabetical order).

HJH:
The first and last letters are the same, H.
The middle letter J is two letters after H in the alphabet (H → J is +2 in alphabetical order).

Identifying the Pattern:
All options have the first and last letters the same, but:
For TRT, the middle letter is two letters before the repeated letter T (-2).
For BDB, QSQ, and HJH, the middle letter is two letters after the repeated letter (+2).
Conclusion:
The odd one out is TRT because its middle letter does not follow the same alphabetical sequence as the other options.
Final Answer: TRT.
