Caffeine is a chemical compound that stimulates the human central nervous system. Research into the effects of caffeine has been performed by a myriad of companies from different places around the world, and new evidence is published every few months. High caffeine intakes cause nervousness and insomnia in some subjects while drowsiness and repose are experienced by others. Furthermore, some people report a laxative effect while in others it can result in constipation.

Which of the following conclusions is most strongly supported by the information above?

A) Since there is not enough consistency with regards to results, research of such a chemical is not advantageous and should be discontinued.
B) The individuality of human subjects creates difficulty when attempting to form a definitive judgement about the symptoms of caffeine.
C) Caffeine does not affect the central nervous system in all people and, therefore, physiological symptoms can also vary.
D) Caffeine can act as an addictive substance causing unpleasant side effects and harm to the human body's basic functions.
E) To conduct more accurate research, examinations should be carried out on larger test groups.

Who's to say it should be discontinued? OOS.

B) The individuality of human subjects creates difficulty when attempting to form a definitive judgement about the symptoms of caffeine.
Definitely hold. There are definitely different and sometimes opposite effects on different subjects.

C) Caffeine does not affect the central nervous system in all people and, therefore, physiological symptoms can also vary.
The last part sounds right, "physiological symptoms can also vary." But the premise clearly states the central nervous system is stimulated.

D) Caffeine can act as an addictive substance causing unpleasant side effects and harm to the human body's basic functions.
Way OOS. We do not know this.

E) To conduct more accurate research, examinations should be carried out on larger test groups
We have no info about test group quantity. We should not make any assumptions on this.

Hope this helps someone.

There are several substances in the brain that work in a yin-yang , some make the brain more awake, others
calms the brain - the caffeine does something that makes the awake substances more expressive, that's how it works

So lets see
Research into the effects of caffeine has been performed by a myriad of companies from different places around the world
High caffeine intake causes
nervousness and insomnia in some subjects while drowsiness
repose are experienced by others.
some people report a laxative effect
while in others it can result in constipation

A) Since there is not enough consistency with regards to results, research of such a chemical is not advantageous and should be discontinued.
No claim has been made about this

B) The individuality of human subjects creates difficulty when attempting to form a definitive judgement about the symptoms of caffeine.
This can be inferred

C) Caffeine does not affect the central nervous system in all people and, therefore, physiological symptoms can also vary.
This wasn't even tested here

D) Caffeine can act as an addictive substance causing unpleasant side effects and harm to the human body's basic functions.
No claim has been made about this

E) To conduct more accurate research, examinations should be carried out on larger test groups
How does this even matter ??

Isn't option B too generic for an answer?
I chose C since in the premise, the evidences show that not all the people have their central nervous systems impacted.

Can someone explain what am I missing here?

Thanks.
