In the following question, select the odd letter/letters from the given alternatives.

JJLP DDFK TTVZ RRTX

DDFK

THE LOGIC; 1) JJLP, J → (+0) → J → (+2) → L → (+4) → P 2) DDFK, D → (+0) → D → (+2) → F → (+5) → K 3) TTVZ, T → (+0) → T → (+2) → V → (+4) → Z 4) RRTX, R → (+0) → R → (+2) → T → (+4) → X Thus, DDFK is the odd one.
