@msaber,

Happy to help!

The stimulus is basically telling us that there are some symptoms of
mental illness that are affected by various organic factors. However,
in looking around the globe, there's a large variation in the
incidences of these symptoms. Because of this, the argument concludes
that the organic factors that are actually affecting people vary
throughout the world.

So we know that symptoms vary a lot from culture to culture. While
it's true that organic factors varying could be the reason for this,
it's possible that they're not the reason. Perhaps some culture simply
reveals certain things more than others do. The argument is ignoring
the fact that it's possible that the mental illness symptom incidences
are caused by things that aren't organic.

(C) says, "fails to consider the possibility that cultural factors
significantly affect how mental illnesses manifest themselves in
symptoms"

(C) describes a type of non-organic variable that might be causing the
variation in mental illness symptoms, and this is something that the
argument ignores. This is why (C) is the correct answer.

Hope this helps—let us know if you have any more questions!
