The correct answer is letter D

Depression is much more than a deep sadness. The victims of this disease have changes in the brain neurotransmitters involved in the feeling of well-being. While in people with normal brain chemistry these substances face temporary casualties in times of sadness, in the depressed they are always on the floor. In depression, there are altered levels of norepinephrine and serotonin. And the drugs used in the treatment correct the changes in these neurotransmitters, promoting chemical rebalancing in the brain.

Neurotransmitters are molecules that make communication between neurons. One of them, serotonin, is directly related to mood. To connect the cells, these molecules fall into a space between them, called the synaptic cleft. In depressed people there is less of these messengers among neurons. To make matters worse, a natural mechanism for reusing neurotransmitters pushes some of these molecules back into the cell. Result: their level plummets, also dropping the mood.
