Correct answer: "Nicotine is a chemical that alters how an individual feels."
Brief explanation: nicotine quickly acts on nicotinic acetylcholine receptors in the brain, changing brain chemistry and releasing neurotransmitters (including dopamine and norepinephrine). Those changes produce immediate physical effects and mood changes and can lead to dependence — so the other statements are false.
