One would think that it would be "the apparent disappearance of matter in flames was an illusion," but since this refers to a scientific fact about the natural world, it wouldn't change between 1774 and today. Thus the present tense is needed, and D and E are eliminated.

B and C are eliminated on the basis of semantics. C implies that it is the ILLUSION that is apparent and not the disappearance of matter in flames. That is inconsistent with the original and logical meaning. B also shifts the meaning to something different and illogical, implying that it is the MATTER that disappears ("that apparently disappears in flames" has become a relative clause modifying the noun, "matter").

I was confused between A and E, the remaining answers are not what the author is implying. However, im not sure i completely agree with your logic of using present tense, since if the discovery was in the past and it still holds true, it would not be simple present rather it would be present perfect has/have+ past participle but none of the choices give us that.
Any other reasoning to choose A over E

Present perfect is not, strictly speaking, about something that happened in the past and still holds true. That is often the case, but the stricter definition is this: present perfect is a present tense that refers to past events with some sort of anchoring reference in the present moment. This generally takes the form of a consequence:

- "I've been bleaching my hair for years!" given as a response to someone noticing that my hair is platinum blonde and badly damaged (the consequence)

- "I've lived in Paris for four years!" when a Frenchman notices that although I have an accent I speak French very well (the consequence)

- "I've lived in Florida before!" when a friend from across town tells me that he plans to move to Florida (as a consequence of my having lived there already, I am equipped to relate to his present/future experience)

The present perfect, by itself, does imply something finite about the action in question. Thus you would never say, "The apparent disappearance of matter in flames has been an illusion" because this is a scientific FACT, true for all time.

Between A & B, I chose B very carelessly. However, I found why choice B wrong; the reason is the meanings of the sentence, "the matter" cannot be "the illusion".

d) it was an illusion that there is an apparent disappearance of matter in flames.

e) it was an illusion that matter apparently disappears in flames.

From the dictionary: 1) Apparent = Appearing as such but not necessarily so
2) Apparently = Unmistakably; visibly clear; in an evident manner

B and C distort the original meaning.
D and E have pronoun referent error and tense error.
A is the correct answer choice.

A is correct even though C looks correct. C actually changes the meaning.

D and E are not grammatical
it was ilusionary that -clause
is idiomatic

it is good that-clause , is correct
it is evidence that-clause, is correct if "it " is real subject not fake subject.

am I correct?

The modifiers in all other choices change the meaning of the sentence, making this sentence, in some cases, illogical.

This one was quite tricky. I picked C because there are some harder SC questions in which the original sentence is gramatically correct but is illogical and therefore has a meaning issue.
The way 'apparent' is usually used I thought it must mean 'obvious'. If disappearance is obvious how can it be an illusion? However, if we translate apparent as 'observable' it is clear that A is ok.
