Ok - this is a parallelism question, but you have to be careful to make sure you are looking at the correct elements to be made parallel.

This question is presenting a three item list that needs to be in this format to be correct "X, Y, and Z": to revamp..., institute..., and create. Note that with infinitive parallelism we can drop the "to" before the 2nd & 3rd items in the list. Interestingly, answer choices A, B, and C have an improper structure of "X, Y, Z" - no "and". We need an "and" somewhere in the list to have an actual sentence*. That eliminates A, B, and C without having to deal with participle vs. infinitive in the parallel structure.

Looking at D and E, there is an idiom choice (you could view it as a meaning choice) between "for taking" and "to take". Looking at the context of the sentence, we need to use "to take" to generate the proper meaning that the non-government organization (looks like the word "organization" was inadvertently left off choices D&E) will be the thing that actively "takes" charge.

[*Quick note: We could use the participle "creating" and be grammatically correct with a structure of X and Y, participle. In this format the participle isn't part of the list by rather a modifier for the preceding clause. On this question, they don't provide the "X and Y, participle" format as an option and frankly if they did it would be grammatically correct but the meaning would be flawed.]
