Please explain WHY an answer is wrong.

The sentence is using the idiom either X or Y. The only case which satisfies parallelism between X and Y is D -
either become too crowded, <-ing modifier>, or spread too far outward, <-ing modifier>.
The other choices donot satisfy parallelism. B,C use participles and don't have a main verb in X and Y both. A and E use AND instead of OR

The root systems of most flowering perennials either become too crowded, which results in loss in vigor, and spread too far outward, producing a bare center.
1.The root systems of most flowering perennials does one out of two things in either X or Y way they either
become too crowded or spread too far outward
2. when the root systems of perennials become crowded, it results in loss of vigor and this resulting action is best described in verb-ing form resulting since becoming crowded is an action. Similarly, spreading action result is best represented by producing a bare center in non underlined part of sentence and both verb-ing parts are parallel.
coming to options (A) which results in loss in vigor, and spread which cannot refer to action and loss in vigor is not idiomatic either x or y is structure is disturbed by using and instead of or.
(B) resulting in loss in vigor, or spreading loss in vigor as in A is not resolved yet spreading is not parallel to become
(C) with the result of loss of vigor, or spreading with the result is awkward spreading is not parallel to become
(D) resulting in loss of vigor, or spread correct
(E) with a resulting loss of vigor, and spread errors as in A and B repeat here

The word "either" is great to see, especially in the non-underlined portion of a SC question, because it is part of a reliable idiom. If you see the word 'either' in the non-underlined portion, you know two things:
1) The work 'or' will show up later in the sentence 2) What follows the 'either' and what follows the 'or' will be in parallel form
A and E can be eliminated because they don't have an 'or'.
B and C can be eliminated because what follows the 'or' (spreading) is not parallel with what follows the 'either' (become).

Hello, I have applied the structure here in this question "Either X or Y'". Since this question includes parallelism too, I have applied that too and marked the option B as my answer choice considering "ing" then how my answer became wrong? Please advise.

The parallel structure, as you have correctly identified, is EITHER X OR Y. Here X = become (a verb). So Y should also be verb.
In B, present participle "spreading" is wrongly made parallel to verb "become". In D, verb "spread" is correctly made parallel to verb "become".

The root systems of most flowering perennials either become too crowded, which results in loss in vigor, and spread too far outward, producing a bare center.
Issues: Idiom | Parallelism
Analysis: 1. To complete the non-underlined "either...", we need "or.." to complete idiom "either X or Y" 2. Also, X and Y in idiom should be parallel.
(A)which results in loss in vigor, and spread - "which" does have referent - "and" is unidiomatic
(B) resulting in loss in vigor, or spreading - "spreading" not parallel "become"
(C) with the result of loss of vigor, or spreading - "spreading" not parallel "become"
(D) resulting in loss of vigor, orspread
(E) with a resulting loss of vigor, and spread - "and" is unidiomatic

The root systems of most flowering perennials either become too crowded, which results in loss in vigor, and spread too far outward, producing a bare center.
There are two flaws in the original sentence. 1. The idiom eitherAorB is not used 2. The phrase 'loss in vigor' is incorrect.
Using 1, we can eliminate A & E
Using 2, we can eliminate B
Answer choice C uses a redundant double preposition 'of loss of vigor', hence eliminate.

(A) which results in loss in vigor, and spread (B) resulting in loss in vigor, or spreading (C) with the result of loss of vigor, or spreading (D) resulting in loss of vigor, or spread.....correct option (E) with a resulting loss of vigor, and spread
Here we can see the usage of idiom either X or Y. The only case which satisfies parallelism between X and Y is D -
