Which neurotransmitter is associated with happiness and social behavior?A) NorepinephrineB) DopamineC) SerotoninD) Cortisol

The neurotransmitter most commonly associated with happiness and social behavior is C) Serotonin.

Serotonin plays a key role in regulating mood, anxiety, and overall feelings of well-being. Research indicates that higher levels of serotonin are linked to improved mood and emotional stability. This neurotransmitter helps to facilitate social behavior and can influence how we interact with others. While dopamine is also related to feelings of pleasure and reward, it is more closely associated with motivation and the reward pathway rather than social behavior specifically. Norepinephrine is involved in the body's stress response, and cortisol is a hormone associated with stress rather than happiness. Therefore, serotonin is the best answer to the question.
