from PREP:
Under high pressure and intense heat, graphite, the most stable form of pure carbon, changes into the substance commonly referred to as diamond and remaining this way whether or not the heat and pressure are removed.
(A) remaining this way whether or not
(B) remaining like that even as
(C) remaining as such whether or not
(D) remains in this way although
(E) remains thus even when
confused with D and E. Can anyone help?

The "and" before the underline signals that this question is testing PARALLELISM.
If we strip away all modifiers, we're left with:
...graphite... changes into... a diamond and remaining this way...
The correct version must be "changes and remains." Eliminate A, B, and C. Let's examine D and E:
(D) remains in this way although
- "remains in this way" is not idiomatic. We'd have to say "remains this way."
- "although" changes the meaning from something that hypothetically could happen into something that definitely did happen. Do we know that heat and pressure are removed from every diamond? Surely there are diamond still in pressurized-and-heated form in the world.
(E) remains thus even when
This maintains parallelism and maintains the correct meaning.
The answer is E.

A, B and C: graphite changes...and remaining
Here, changes (verb) and remaining (modifier) are not parallel forms.
Eliminate A, B and C.
Generally, in this way refers to the METHOD used to achieve a desired result.
D: Under high pressure and intense heat, graphite changes...into diamond and remains in this way although the heat and pressure are removed.
Here, the subject -- graphite -- does not use a method to achieve a desired result, so the usage of in this way is unwarranted.
Also, the two portions in red contradict each other, implying that graphite is UNDER PRESSURE AND HEAT although THE HEAT AND PRESSURE ARE REMOVED.
Eliminate D.
The correct answer is E.
OA: Under high pressure and intense heat, graphite, the most stable form of pure carbon, changes into the substance commonly referred to as diamond and remains thus even when the heat and pressure are removed.
Here, remains thus = remains in this STATE.
Conveyed meanings:
Under high pressure and intense heat, graphite changes into the substance known as a diamond.
Graphite remains IN THIS STATE -- in other words, the yielded diamond does not change back into graphite -- even when the heat and pressure are removed.
These meanings are logical.
