Select the option that is related to the fifth term in the same way as the fourth term is related to the third term and the second term is related to the first term.
DOLPHIN : ALIMEFK :: GROUP : DOLRM :: SHARK : ?

Given: DOLPHIN : ALIMEFK :: GROUP : DOLRM :: SHARK : ?

Logic: Each letter is subtract by 3 positions in the alphabet.

DOLPHIN: D -3 = A; O - 3 = L; P- 3 = M; H - 3 = E; I - 3 = F; N - 3 = K

So DOLPHIN is written ALIMEFK.

GROUP: G -3 = D; R - 3 = O; O - 3 = L; U - 3 = R; P - 3 = M

So GROUP is written DOLRM.

Similarly, follow the same pattern for SHARK.

SHARK: S - 3 = P; H - 3 = E; A - 3 = X; R - 3 = O; K - 3 = H

So SHARK is written PEXOH.

Thus, the correct answer is (d).
