GMAT Inequalities is a high-frequency topic in GMAT Quant, but many students struggle because the concepts behave differently from standard algebra. Understanding the right rules, patterns, and edge cases can significantly improve both speed and accuracy.

OFFICIAL EXPLANATION
THE PROMPT
THE OPTIONS
This subject is hard.
that the group of chemical compounds known as the biogenic amines
-- eliminate that the to clean things up
-- eliminate known as the biogenic amines
That phrase is an essential adjective that modifies chemical compounds and cannot be placed elsewhere
We are left with
. .. group of chemical compounds
Eliminate the prepositional phrase that immediately follows group.
-- chemical compounds is the object of the preposition OF, and the object of a preposition is never the subject of a sentence.
Result?
• Split #1: Subject verb agreement
The subject is group.
Group is a collective noun that takes a singular verb.
Option B uses play, plural.
Eliminate B
• Split #2 - The sentence already suggests uncertainty - avoid redundancy
The phrase it seems probable already tells readers that uncertainty is lurking.
Seems is "soft" word. Probable is an uncertain word.
Option A uses may play
Option D uses might play.
Both suggest uncertainty.
They are virtually identical.
Both are redundant.
Eliminate A and D.
• Split #3 - meaning
No one has taken on option E directly yet.
Understandable. This question looks as though it's concerned with verbs.
It is.
But the meaning of option E is kinda silly as it stands.
The verb has been playing suggests that the biogenic amines just recently started to play a role in causing mental depression (or at some point not too far in the past).
What, the amines started to cause depression only a decade ago? Only 30 years ago? 50 years ago?
Nonsense.
These amines either did play and do play, or did not and do not play, a role in causing depression.
I'm no biologist, but I'm going to bet that biogenic amines have been part of homo sapiens sapiens for a long time.
In other words, although the sentence approaches its claim tentatively, the sentence describes what will probably be a scientific truth.
We need a tentative guess ("It seems probable that") about a general and solid truth (amines play a role in causing depression).
OPtion E conveys the wrong timing.
Eliminate E
The answer is C.
COMMENTS
SKY396 , welcome to SC Butler.
These answers are pretty good.
And by all means trust your instincts: if you read enough, you'll know when a sentence just seems "off" slightly, even if you can't explain why.
I don't see any posts that address option E.
Why is the use of present continuous wrong? (An again, well done for catching something that must have seemed wrong to you.)
Everyone gets smiley faces.
And everyone -- please be safe.

It seems probable that the group of chemical compounds known as the biogenic amines may play an important role in causing mental depression.
The possibility/uncertainty is already taken care of by the phrase "seems probable", so we just need simple present tense without any auxiliary verbs.
Since main subject is "group" => verb "plays"
So C
