Solution and Explanation
In the context of hepatitis B, the "Australian antigen" refers to the surface antigen of the hepatitis B virus (HBV), also known as HBsAg, where "HB" stands for hepatitis B, "s" for surface, and "Ag" for antigen. This antigen is the primary marker used for detecting active hepatitis B infection.
| Antigen | Type |

| Hb S ag | Hepatitis B surface antigen (HBsAg) |
| Hb E ag | Hepatitis B e antigen (HBeAg) |
| Hb D ag | Not a recognized hepatitis marker |
| HbV Dna | HBV DNA - Represents viral genetic material |
In summary, the Australian antigen for hepatitis B is correctly identified as HBsAg, making the correct answer Hb S ag.
