Answer:
"a) The influence people your age have on your decisions and behavior"
Explanation:
a) The influence people your age have on your decisions and behavior
- Peer pressure because peer pressure is "the influence from members of one's peer group" (Oxford Languages).
b) Following your parents' rules
- Not peer pressure as you parent's rules do not influence your actions from your peer group
C) Making hard decisions
- You are not influenced (unless you are, but this statement does not say that) so it cannot be peer pressure
