Question

what potential risks are associated with consuming substances that alter brain chemistry?
decreased risk of distorted perceptions
enhanced risk assessment skills
engaging in potentially dangerous behaviors

Explanation:

Substances that alter brain chemistry (like drugs or alcohol) typically impair judgment, perception, and decision - making. "Decreased risk of distorted perceptions" is incorrect as such substances often increase distorted perceptions. "Enhanced risk assessment skills" is wrong because these substances usually reduce one's ability to assess risks. "Engaging in potentially dangerous behaviors" is correct as impaired brain function from these substances can lead to risky actions (e.g., driving under influence, unprotected sex).

Answer:

C. engaging in potentially dangerous behaviors
