Of all the possible disasters

Of all the possible disasters that threaten the upcoming Olympic games, the possibility of forceful winds affecting the rowing venue is maybe the more difficult for analysis.

A.  is maybe the more difficult for analysis.
B.  is probably the most difficult for analysis.
C.  is maybe the most difficult for analysis.
D.  is probably the more difficult for analysis.
E.  is, it may be, the analysis that is most difficult.

The best answer is B.  The sentence compares one thing, forceful winds affecting the rowing venue, to all other possible disasters.  Therefore, the superlative form, most, is required.  The use of maybe is unidiomatic.
