What did the analyst not consider? Three things: 1. the donations, 2. the project expense and 3. The ways in which these donations and project expenses affected one another. This is what D makes out IMO. The plural pronoun– They - refers to the donations and expenses.

E what does – each - stand for? Analyst? Can’t be. There is no other singular noun for the word -each - to refer to.

Secondly how correct is – each affect- a plural verb- affect - for the singular -each. - ?

Thirdly what are those -some other -. can't just decipher the - some other – E is wrong according to me

D therefore

well
using you logic, one can assume EACH can refer to donations and expenses.
and since when EACH has to refer to singular nouns, actually how can you even attach EACH to singular noun.
P.S.: I don't like E and D,
I don't like the whole question.

I could be wrong, but this is how I feel about it.

d.they can refer to charitable donation

@Elevinty: for your question “and since when EACH has to refer to singular nouns, actually how can you even attach EACH to singular noun.”
Given below is link: https://www.thefreedictionary.com/each

If you still have any doubts, please contact me again. I have materials up to the neck on this.

Please rest assured that I am only answering your question.

In a sentence, almost all the times 'nor' comes in combination of 'neither'. Since statements A and B have "nor" with out a "neither" they can be ruled out.

Reference to 'next' in C is not logical since the sentence wasn’t intending to talk of chronology of anything.
 
D is more obvious because the sentence is meaning to talk of two things mentioned in the first sentence as opposed to E, where it talk of these two in relation to something else.

Ans: D

Perhaps I wasn't clear before or I just implied totally different meaning from what I've been trying to say.
In the link that you are providing, EACH is attached to a single noun, but that noun is a part of a group. What I was trying to say is that attaching EACH with a single noun that can't be a part of a group is clearly nonsensical, i.e., you can't say each furniture, you would say each piece of furniture.

on a personal note: am enjoying this discussion.

Answer for me is (D)
Can't have a double-negative boy.

I will go with D.

@elevinty: I may be wrong but I think 'they' cannot refer to the analyst because the sentence is about a single analyst - a single person. 'They' will refer to something plural which are the 2 ideas presented. If the analyst has to be referred the correct pronoun to use would be 'he/she' whatever but not 'they'.

OFFICIAL EXPLANATION:

(Quantity Word) Remember that the phrase “each other” must be used when referring to two persons or things. Whenever the number involved is more than two, the correct phrase to be used is “one another.”

The non-underlined part of the sentence talks of the company’s “donations” and “expenses,” implying more than a single donation and expense. So, the use of the phrase “each other” to refer to them is ungrammatical and (A) is wrong.

(B) and (E) also contain the same error, and can be discarded for that reason alone.

Though (C) is shorter than (D), it has the error of using the conjunction “where” (which should be used only to refer to a place) to refer to “way” (meaning “manner” in the given context). Moreover, it is not intention of the author that every donation must be compared only to the “next” not to all. So, (C) is wrong.

(D) has no error, completes a clear, cogent, unambiguous and grammatical sentence, and is the answer.

Correct answer D

The analyst didn’t consider the company’s charitable donations, its volunteer project expenses, nor the ways one affects the other.

1st split nor/or - didn't consider with nor creates double negative A and B - out

2nd split where / in which - where can modify only places - C out

3d split one affects the next - wrong construction / each affect some other - incorrect structure / affect one another
Each other is used for two things; one another for more than two - in our case donations and projects are plural - C and E - out

I don't understand how use of nor creates a double negative when the dictionary definition is "used before the second or further of two or more alternatives (the first being introduced by a negative such as ‘neither’ or ‘not’) to indicate that they are each untrue or each do not happen".
