Which statement about Hepatitis B is true?

• A. It is spread mainly through inhalation of aerosolized particles.
• B. It is a virus that affects the liver and has an incubation period of 2-6 months.
• C. It cannot be prevented by vaccination.
• D. It never leads to chronic infection.

Answer: (B)

Hepatitis B is a virus that infects the liver, and its time from exposure to detectable illness or markers is relatively long, typically about two to six months. This incubation range is a standard description for Hepatitis B and helps explain why symptoms or lab findings can appear well after contact. Vaccination exists and is effective at preventing Hep B, and infection can become chronic, especially when acquired early in life. The other statements don’t fit because transmission is not mainly through inhalation of aerosolized particles, vaccination can prevent Hep B, and chronic infection can occur in a meaningful number of cases.
