OG73 之迷惑

73. The British Admiralty and
the War Office met in March 1892 to consider a possible Russian attempt to
seize Constantinople and how they would
have to act militarily to deal with them.

(A)  how they would
have to act militarily to deal with them

(B)  how to deal with
them if military action would be necessary

(C)  what would be
necessary militarily for dealing with such an event

(D)
what military action would be necessary in order to deal with such an event

(E)  the necessity
of what kind of military action in order to take for dealing with it

1. 不可以

恩,我也不明白,哪位NN解答一下?

(C) what would be necessary militarily for dealing with such an event

这里militarily (adv.)修饰 necessary (a.) 翻成中文也是很拗口的 军事地必须的   

另外，我觉得（C）将原题 act / action的意思给去除了，改变句意，应该也可以做为参考的依据

请指正！
