Out of the four letter-clusters listed, three are alike in some manner and one is different. Select the odd one.

Let's analyze all the options:

Logic: Each letter in each option increase by 2 places in English alphabet except option (d)

(a) SUWY
S + 2 = U
U + 2 = W
W + 2 = Y
(+2, +2, +2 pattern)
(b) MOQS
M + 2 = O
O + 2 = Q
Q + 2 = S
(+2, +2, +2 pattern)
(c) BDFH
B + 2 = D
D + 2 = F
F + 2 = H
(+2, +2, +2 pattern)
(d) JLMP
J + 2 = L
L + 1 = M  (Breaks pattern)
M + 3 = P
(+2, +1, +3 pattern, different from others)
Odd one out: (d) JLMP  Because it does not follow  +2 pattern).

Thus, the correct option is (d) JLMP
