Can you help me in answering below question
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
(E) that they can withhold public disclosure of
In choices B and C, the preposition “for” is used wrongly in place of the “-ing” modifier to introduce the phrase describing powers.
In choice C withholding disclosure is wordy and incorrect, since it is the identities that are to be withheld. Also, “withhold………of” is an incorrect idiom. The right usage is “withhold from”
The plural pronouns “them” in D and “they” in E do not agree with the singular “Central Intelligence Agency”
Choice A is the right answer: “enabling” clearly modifies powers, it refers logically and grammatically to the Central Intelligence Agency, and “to withhold from the public” is correctly phrased.
