Alcohol affects which of the following body parts?

Alcohol affects multiple body parts, and option B accurately reflects this by including the brain, liver, stomach, and kidneys.

The brain is considerably impacted by alcohol, as it influences cognitive functions, motor skills, and decision-making. This is why even small amounts can impair an individual's ability to drive and respond to situations effectively.

The liver is affected because it is the primary organ responsible for metabolizing alcohol. Chronic alcohol consumption can lead to liver diseases, including fatty liver, hepatitis, and cirrhosis.

The stomach is involved as alcohol can cause irritation and inflammation, leading to potential gastric issues and influencing how food is digested.

Lastly, although the kidneys aren't the primary focus in discussions about alcohol, they do play a role in filtering blood and maintaining fluid balance in the body, which can be disrupted by alcohol consumption.

Each of these body parts plays a significant role in processing and responding to alcohol, illustrating why option B is the most comprehensive and accurate response.
