OA is D ...why not C?
I am not getting the right results in CR.Need help

Baking for winter holidays is tradition that may have a sound medical basis. In midwinter, when days are short, many people suffer from a specific type of seasonal depression caused by lack of sunlight. Carbohydrates, both sugars and starches, boost the brain’s levels of serotonin, a neurotransmitter that improve the mood. In this respect, carbohydrates act on the brain in the same way as some antidepressants. Thus, eating holiday cookies may provide an effective form of self-prescribed medication.
Which one of the following can be properly inferred from the passage?
(A) Seasonal depression is one of the most easily treated forms of depression.
(B) Lack of sunlight lowers the level of serotonin in the brain.
(C) People are more likely to be depressed in midwinter than at other times of the year.
(D) Some antidepressants act by changing the brain’s level of serotonin.
(E) Raising the level of neurotransmitters in the brain effectively relieves depression

The argument says winter is a cause for depression. But there is nothing in the passage that explains the 'likelihood' (more or less likely) of people getting depressed in winter. So C is not the correct choice.

There are two statements in the passage when read together point to D.

Carbohydrates, both sugars and starches, boost the brain’s levels of serotonin

carbohydrates act on the brain in the same way as some antidepressants

Based on these statements one can safely say antidepressants change brain's seotonin levels.

Hope that helps!
