Polio is caused by A. Bacteria B. Virus C. Fungus D. Protozoa

The correct answer is: B. Virus

Polio is an infectious disease caused by a virus. It enters the body through the mouth and multiplies in

the intestines. The virus can then spread to the brain and spinal cord, causing paralysis.

Bacteria are single-celled organisms that can cause a variety of diseases, including pneumonia, strep throat, and

tuberculosis. Fungi are multicellular organisms that can cause diseases such as athlete’s foot, ringworm, and yeast infections. Protozoa are single-celled organisms that can cause diseases such as malaria, sleeping sickness, and toxoplasmosis.

Polio is a serious disease that can be prevented by vaccination. The polio vaccine is a safe and effective way to protect yourself and your children from this disease.
