Answer:

The correct answer would be option A, The antibiotic kills harmful bacteria but not human cells.

Explanation:

Antibiotics are the medicines given to a person who gets sick due to a bacterial infection in his body. Bacterial Infection can not be treated without using the antibiotic medicines because antibiotics are the only medicines that kill the harmful bacteria inside a human body while keeping the human cells alive and healthy. Antibiotics do not harm the body cells. They just work on the bacterial infection and kill the bacteria. Other functions of the body are not disturbed by taking the antibiotics.
