The answer is C. Cancer.
Hepatitis B, tetanus, conjunctivitis, and measles are all infectious diseases. Cancer is not an infectious disease. It is a disease in which abnormal cells divide uncontrollably and destroy healthy tissue.
Hepatitis B is a viral infection that affects the liver. It can cause acute hepatitis, which is a short-term illness, or chronic hepatitis, which is a long-term illness. Chronic hepatitis B can lead to cirrhosis of the liver, liver cancer, and death.
Tetanus is a bacterial infection that causes muscle stiffness and spasms. It is often called lockjaw because it can cause the jaw to lock shut. Tetanus can be fatal if not treated.
Conjunctivitis is an inflammation of the conjunctiva, which is the thin, clear membrane that lines the eyelids and covers the white part of the eye. Conjunctivitis can be caused by viruses, bacteria, allergies, or irritants. It is usually not serious, but it can be very uncomfortable.
Measles is a viral infection that causes a rash, fever, and cough. It is a highly contagious disease that can be serious, especially in young children. Measles can be prevented by vaccination.
