A can be easily eliminated for the reason that money is uncountable, so proper use is "amount(-s) of money" not "numbers of money"
In addition, "techniques that enabled political candidates with cash-strapped budgets to be able to reach" is unnecessary wordie and redundant.

I cannot find strong reason for elimination, but in comparison with D ("succeed" vs "be successful"), D wins: verb form is more preferable.

Meaning is changed and now conveys that "reach" results in "succeeding". It looks that the meaning in A is more appropriate: "reach" and "succeed" are two parallel actions.

- correct choice. The only issue with this choice I have is that in other thread, in which use of "ENABLE" discussed, it was pointed out that the idiomatic use is ENABLE + BARE INFINITIVE. But none of options provides us with an infinitive without "to" here

"enabled.. to be able" leads to redundancy

With the advent of YouTube, Facebook, and Flickr, many savvy political consultants undertook revolutionary micro-targeting and get-out-the-vote techniques that enabled political candidates with cash-strapped budgets to be able to reach numerous likely voters and succeed in raising large numbers of money from enthusiastic and committed supporters in a short period of time.

(A) cash-strapped budgets to be able to reach numerous likely voters and succeed in raising large numbers of money -- 1. To be able to reach is wordy and redundant. 2. Large numbers of money is unidiomatic.
(B) cash-strapped budgets to reach numerous likely voters and be successful in raising large amounts of money -- succeed is preferable to be successful as per V-A-N rule.
(C) cash-strapped budgets to reach numerous likely voters, succeeding in raising large amounts of money -- Succeed is the essence of the sentence. To use a modifier 'succeeding' for that function is unstylish.
(D) cash-strapped budgets to reach numerous likely voters and succeed in raising large amounts of money-- the correct choice.
(E) cash-strapped budgets to be able to reach numerous likely voters and succeed in raising large amounts of money-- to be able to reach is wordy.

The right answer is option D.

(A) cash-strapped budgets to be able to reach numerous likely voters and succeed in raising large numbers of money
to be able is wordy and not concise. There is no need to add to be able to sentence since to reach logically means to be able to reach. large numbers of money? No, it should rather be large amounts of money. Eliminate option A.

(B) cash-strapped budgets to reach numerous likely voters and be successful in raising large amounts of money
Option B is grammatically correct. Let's keep option B for now.

(C) cash-strapped budgets to reach numerous likely voters, succeeding in raising large amounts of money
Logically, succeeding in raising large amounts of money modifies political candidates with cash-strapped budgets. It could also modify the subject of the sentence savvy political consultants. Option B is not as clear as options B and D. In addition, by not making the act of raising large amounts of money parallel to to reach numerous likely voters, the sentence implies that the main focus of using Facebook, YouTube, and Flickr is just to reach out to potential voters and this is contrary to the meaning of the sentence. Eliminate option C.

(D) cash-strapped budgets to reach numerous likely voters and succeed in raising large amounts of money
Correct. Option D is parallel and more concise than option B. This is because the verb succeed is more concise compared with be successful. Eliminate option B and keep option D.

(E) cash-strapped budgets to be able to reach numerous likely voters and succeed in raising large amounts of money
The same error in option A is present in option E although large amounts of money is rightly used in option E. Eliminate option E.

The best answer is option D.

OFFICIAL EXPLANATION

(1) The sentence must be constructed such that corresponding consequences of an action are parallel. Specifically, the sentence should read enabled political candidates with cash-strapped budgets to x and y where x and y are parallel.

(2) The phrase to be able to z is redundant and should be replaced by to z

(3) The phrase numbers of money should be amounts of money since number is only used when the object in question can be counted and money cannot be counted (i.e., you do not say 1 money, 2 money, 3 money). Note: By comparison, dollars can be counted (i.e., you would say 1 dollar, 2 dollars, 3 dollars) and as a result, we would say: the number of dollars.

A. the phrase to be able to reach is redundant and can be shortened as follows: to reach; large numbers of money is not grammatically correct since money itself cannot be counted and, as a result, amount should be used instead

B. the phrase to reach...and be successful is not parallel

C. this sentence is set up such that succeeding modifies reaching voters instead of being a separate action on its own

D. the phrase is parallel (i.e., to reach...[to] succeed); to be able to reach is replaced by the shorter to reach

E. the phrase to be able to reach is redundant and should be replaced by to reach

Bunuel can you please explain how " to reach " and "succeed " are parallel. when can we assume to add a "to" before a verb
