Final answer:
The dopamine release and generation of positive feelings are primarily triggered by social interactions and rewards. Stimulants, including opioids and alcohol, can also induce dopamine release but often come with risks of abuse and addiction.
Step-by-step explanation:
Dopamine is a neurotransmitter that plays a significant role in feelings of pleasure, motivation, and reward. Certain activities and substances can trigger the release of dopamine in the brain. The correct answer to what triggers dopamine release and generation of positive feelings is c) Social interactions and rewards. Substances such as opioids and alcohol can also cause the release of dopamine, leading to euphoric high feelings. However, these are also associated with abuse potential and addiction. Other drugs like stimulants act as agonists of dopamine neurotransmission, and they include substances like cocaine and amphetamines. An important note is that not all drugs causing dopamine release are considered beneficial, as they often have adverse effects such as the potential for dependence and abuse.
