Which of the following is the Hepatitis B surface antibody indicator?

Explanation:
Immunity to hepatitis B is indicated by the surface antibody, anti-HBs. This antibody targets the hepatitis B surface antigen (HBsAg) and signals protective immunity, usually arising from vaccination or recovery from infection. In contrast, the presence of the surface antigen (HBsAg) means an active infection. The core antibody (anti-HBc) shows past or current exposure to the virus, with IgM indicating a recent infection and IgG suggesting longer-term exposure. Viral DNA (HBV DNA) reflects active viral replication and helps gauge viral load. So the surface antibody marker specifically identifying hepatitis B surface immunity is anti-HBs.
