The correct answer is (c), virus.
Hydrophobia is a symptom of rabies, a viral disease that affects the central nervous system. It is caused by a virus called Lyssavirus, which is transmitted through the bite of an infected animal. The virus attacks the brain and spinal cord, causing symptoms such as anxiety, confusion, hallucinations, and paralysis. In severe cases, it can lead to death.
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 giardiasis.
Rabies is a preventable disease. The best way to prevent rabies is to avoid contact with wild animals, especially bats. If you are bitten by an animal, it is important to seek medical attention immediately. There is a vaccine that can prevent rabies, but it must be given before symptoms appear.
