You were right!

We're given a bunch of information in this argument. We have to check each answer choice back against the relevant portion of the argument (if any). The comparison made in lines 7-9, allows us to infer answer choice (D).

Incorrect Answers
(A) is out of scope. Ease of treatment?
(B) is very tempting. We know that a certain treatment for a disorder, which is caused by a lack of sunlight, works by increasing one's level of serotonin. But that doesn't ensure that the lack of sunlight caused the disorder by reducing serotonin levels.
(C) sounds likely, but is really out of scope. The argument is about a specific type of depression, while this choice is about all depression.
(E) is stated too strongly. The comparison between (antidepressants) and (sugars and starches) does not establish that sugars and starches (which raise the level of neurotransmitters) are an effective treatment of depression.
