Answer 1

The correct answer is c) 60% of all people who experiment with tobacco or nicotine will become addicted to it. This activation of the brain's reward system leads to pleasurable feelings and reinforces the desire to continue using nicotine

Step-by-step explanation:

The nicotine in tobacco products is indeed one of the most addictive substances known to man. It is estimated that approximately 60% of all people who experiment with tobacco/nicotine will become addicted to it.

Nicotine exerts its addictive effects by interacting with acetylcholine receptors in the brain, resulting in increased activity of dopaminergic neurons in the midbrain reward system. This activation of the brain's reward system leads to pleasurable feelings and reinforces the desire to continue using nicotine.
