The correct answer is C, nicotine increases heart rate.

Nicotine is a stimulant drug found in tobacco products like cigarettes and chewing tobacco. When nicotine enters the body through smoking or chewing tobacco, it causes a cascade of chemical reactions.

To understand how nicotine affects the body, we need some knowledge of biology. Nicotine activates certain receptors in the brain known as nicotinic acetylcholine receptors. When these receptors are stimulated by nicotine, they release neurotransmitters like dopamine, norepinephrine, and serotonin.

Dopamine is a neurotransmitter associated with pleasure and reward. It gives a pleasurable sensation, making nicotine addictive. Norepinephrine is a neurotransmitter that increases heart rate, and serotonin affects mood and appetite.

So, when nicotine enters the body, it stimulates the release of dopamine in the brain, which causes a pleasurable sensation. At the same time, norepinephrine is released, leading to an increase in heart rate.

In summary, nicotine affects the body by increasing heart rate due to the release of norepinephrine in the brain. This increased heart rate can cause various health issues for individuals who use tobacco products.
