Correct answer: C
The Logic: Each letter of the word is shifted by an alternating add/subtract pattern of consecutive natural numbers: -1, +2, -3, +4, -5, +6, -7.
Verifying the given pair REQUEST -> QGNYZYM:
R - 1 = Q
E + 2 = G
Q - 3 = N
U + 4 = Y
E - 5 = Z
S + 6 = Y
T - 7 = M
So REQUEST is coded as QGNYZYM. The fourth term OTBHDIM is therefore the code of the missing word, so we reverse the shifts (+1, -2, +3, -4, +5, -6, +7) on OTBHDIM:
O + 1 = P
T - 2 = R
B + 3 = E
H - 4 = D
D + 5 = I
I - 6 = C
M + 7 = T
The missing word is PREDICT. (Check: applying -1, +2, -3, +4, -5, +6, -7 to PREDICT gives back OTBHDIM.)
