1.        By a vote of 9 to 0, the Supreme Court awarded the Central Intelligence Agency broad discretionary powers enabling it to withhold from the public the identities of its sources of intelligence information.

(A) enabling it to withhold from the public

(B) for it to withhold from the public

(C) for withholding disclosure to the public of

(D) that enable them to withhold from public disclosure（A）

(E) that they can withhold public disclosure of

186, og-222, sec10-12

Choice A is best: enabling... clearly modifies powers, it refers logically and grammatically to the Central Intelligence Agency, and to withhold from the public is concisely and idiomatically phrased. In choices B and C, the preposition for is used unidiomatically in place of the “-ing” modifier to introduce the phrase describing powers. In choices C, D, and E, withholding disclosure is wordy and imprecise, since it is really the identities that are to be withheld. The plural pronouns them in D and they in E do not agree with the singular Agency, and that in E mistakenly introduces a new independent clause rather than a modifying phrase for powers

我想请问一下，为什么b不行?

og解释没看懂，讨论中也没详细说明。

有人说:b中it指代句中主语，从逻辑意思来看他应该指代CIA,所以错？
