Depressed mood states are linked to
low levels of serotonin and
low levels of norepinephrine.
It has been shown that serotonin and norepinephrine are involved in depression, the deficit in either neurotransmitter can cause depression. Thus, these neurotransmitters are targeted in antidepressants.

Information is encoded in DNA, then copied onto RNA during transcription. Then, ribosomes convert the information carried in RNA into a protein, in the process of translation. Also, A and D could be ruled out because DNA and RNA are solely involved with proteins, but polysacchariades are chains of sugars.
