GMAT CLUB's Official Explanation:

A. “Wasting” is wrongly made parallel to “teaching” - “waste” must be parallel to “strive”: The teachers strive to concentrate on teaching rather than waste time on disciplining.

B. The meaning is distorted because “to reduce” is wrongly made parallel to “to introduce” - option B implies that the management intends to introduce a new way and in addition intends to reduce burden, whereas the original meaning is the new way will be driven by … and reduce…..: Thus “reduce” should be parallel to “be driven”. In the other words it should be clear that the new way will reduce the burden.
“To waste” is wrongly made parallel to “to concentrate” - “waste” must be parallel to “strive”: The teachers strive to concentrate on teaching rather than waste time on disciplining.

C. The pronoun “it” is ambiguous. By virtue of parallelism, “it” may be considered to refer to “management” (both are subject of two clauses of the same sentence), but in such case the meaning of the original sentence is distorted. The original meaning is that the new way (and not the management) will encourage, 
“While” wrongly introduces a contrast where there is none.
 
D. Correct.  “Encourage” and “reduce” are parallel. “Strive” and “waste” are parallel. The positioning of the modifier “that” is also correct although it does not touch the modified noun “way” - here we see a typical example of an exception to the modifier touch rule because another vital prepositional modifier “of disciplining the student” comes in between.

E. The pronoun “they” has no proper antecedent. The students will not reduce the burden on the teachers, the new way will.
“While” wrongly introduces a contrast where there is none.
“Wasting” is wrongly made parallel to “teaching” - “waste” must be parallel to “strive”: The teachers strive to concentrate on teaching rather than waste time on disciplining.

A. of disciplining the students that will encourage them to be responsible and self-motivated and reduce the burden on the teachers who strive to concentrate on teaching rather than wasting
Parallelism error; teachers who strive to  . "rather than" is our parallelism trigger and we have a two incorrectly parallel elements; infinitive (concentrate) and a gerund (wasting)

B. of disciplining the students that will be driven by responsibility and self-motivation and to reduce the burden on the teachers who strive to concentrate on teaching rather than to waste
First of all meaning is a little bit off; "a new way... that will be driven by responsibility and self motivation"? I think we can do better than that
Although parallelism may seem ok at first glance, it is not ok from a logical stand point;
Management intends to introduce....and to reduce... Management doesn't want to do two separate thing; what it really wants is to implement a new way through which students will gain responsibility/self-motivation and teachers will focus on teaching rather than wasting time on controlling the class

C. to discipline the students, while it will encourage them to be responsible and self-motivated and will reduce the burden on the teachers who strive to concentrate on teaching rather than waste
Illogical Meaning; "introduce a new way to discipline the students, while it will encourage them..." this basically tells that management wants to introduce a new way while this very new way encourages students. "While" implies a simultaneity so how is it possible for a "new way" that doesn't exist yet to affect the students?

D. of disciplining the students that will encourage them to be responsible and self-motivated and reduce the burden on the teachers who strive to concentrate on teaching rather than waste
 Correct  There is nested parallelism here; 1) that will   2) teachers who

E. to discipline the students that will be driven by responsibility and self-motivation, while they will reduce the burden on the teachers who strive to concentrate on teaching rather than wasting
a new way that will be driven? neither does it sound extremely illogical nor extremely logical. Also same "while" error but this time it is worse, while students reduce burden? it is the new way that will reduce burden not students for sure

Excellent, logical thinking, but put a bit more thought - Is the parrallelism intended between "strive to concentrate" and "strive to waste"? Does someone strive to waste?

I was between teachers who   rather than   and teachers who strive to   rather than  . So my guess, since you mentioned it, is former the intended parallelism?

I went with answer choice A

I saw 2 parallelism markers

Marker 1 - The new way will encourage (students…etc) and reduce (burden on.. etc)

Marker 2 - Teachers who strive to concentrate on X rather than Y (teaching students rather than wasting time disciplining students)

Last but not least - the management introduces a “new way of achieving this outcome” or “new way to achieve this outcome”

It will be “a new way of achieving this outcome”

Answer Choice B technically has better parallelism structure but I don’t like the way it modifies “the students”

Instead of saying the new way “will encourage them to be more responsible and self-motivated”. Instead, B changes the meaning to “will be driven by responsibility and self-motivation”

Tricky question, especially the parallelism.

Although initially I selected D because I thought "Strive rather than waste" was correct parallelism.
But I think right answer Would be E.

as I think - ; the underlined part correctly modifies students.

"Students that will encourage them" students will encourage themselves? arrr!
