The option B is the correct answer here because of idiom "mistake X for Y".

(A)rising of the moon as a massive missile attack by the Soviets
(B)rising of the moon for a massive Soviet missile attack
(C)moon rising to a massive missile attack by the Soviets
(D)moon as it was rising for a massive Soviet missile attack
(E)rise of the moon as a massive Soviet missile attack

I choosed the right answer B, but I cannot get the difference between the "rising" and "rise".
help me guys.

First, there's an idiom issue here; "mistook X for y," is correct, not "mistook x as y" or "mistook x to y." That allows us to narrow the choices to B and D, and D makes it sound like the moon was rising for an attack, which just doesn't make sense. I think the "rise" versus "rising" issue here is just a common usage difference. You would say "moonrise" or "sunrise," but use the gerund to say "rising of the sun" or "rising of the moon." I don't know if this is such a firm difference that it could be termed an idiom, but it doesn't really matter, since the "mistook x for y" idiom allows us to avoid the issue anyway.
