As quick as is most preferred when describing or comparing

Both "as quickly as possible" and "as quick as possible" are commonly used phrases, and both are grammatically correct.
"Quickly" is the adverb form of "quick," so "as quickly as possible" is technically more precise. However, in colloquial usage, "as quick as possible" is also widely accepted and understood.
Therefore, both versions are grammatically correct, but "as quickly as possible" may be considered slightly more formal or precise.

The correct answer is:
C — as quickly as
So the sentence becomes:
“The exercise must be done as quickly as possible.”
Why?
The verb phrase is “must be done” (done = verb).
When describing how an action is done, we use an adverb, not an adjective.
Quick = adjective (describes a noun)
Quickly = adverb (describes a verb)
Since we are describing how the exercise should be done, we need the adverb quickly.
Why the others are wrong:
A – as quick as ❌ (uses adjective instead of adverb)
B – as quicker as ❌ (wrong comparative structure)
D – as most quick as ❌ (incorrect superlative form)
E – as most quickly as ❌ (wrong structure; “most” is not used with “as…as”)

please I need an official explanation for this because I'm sceptical about the question, why is it not "as quick as possible "
