I think the trick is in the AST and ALT values...it is said that in acute hepatitis there values are very high which is not the case here. This mean that it is chronic. Adding to that, s Ag and e Ag are positive which indicate that it's active infection

It is not a well written question...but I definitely agree with this.

HBsAg +: could be acute or chronic
HBeAg +: active viral replication and high transmissibility.
HBcAB +: IgM for acute and IgG for chronic

As mentioned already ALT specifically should be a LOT higher for it to be acute. In chronic these values come down cause now the damage is occuring slowly rather than extensively.

can you also tell me the difference in fulminant hepatitis (necrosis) and acute hepatitis?
can i tell the difference from lab or symptom?
or is biopsy necessary to distinguish between the two..
