Correct option is C

Logic:
The first position follows the pattern of decreasing by 5.
The second position follows the pattern of increasing by 5.
The third position follows the pattern of decreasing by 5.
First position:
B to W: -5
W to R: -5
R to M: -5
M to H: -5
Second position:
J to O: +5
O to T: +5
T to Y: +5
Y to D: +5
Third position:
R to M: -5
M to H: -5
H to C: -5
C to X: -5
Thus, the next term in the series will be: WOM
