The two neurotransmitters involved in sleep, arousal, and mood are serotonin and norepinephrine. So, the correct answer is d. serotonin and norepinephrine.

Here's why:

1. Serotonin: This neurotransmitter is derived from tryptophan and is involved in many functions in the body. In the brain, serotonin impacts levels of mood, anxiety, and happiness. Irregularities in serotonin levels can lead to depression and other mood disorders. Serotonin also plays a role in sleep because it's a precursor to melatonin, a hormone that's heavily involved in the sleep cycle.

2. Norepinephrine: This neurotransmitter is involved in the body's stress response and is often associated with the fight or flight response. It's also important for attentiveness, emotions, sleeping, dreaming, and learning. Norepinephrine is released into the blood as a stress hormone when the brain perceives that a stressful event has occurred.
