[2025-10-02T01:44:19.743521] [PI reasoning] **Clarifying hepatitis B incubation**

I need to provide a quick answer about the incubation period for Hepatitis B. It's generally between 4 to 26 weeks, but the average is around 60 to 90 days; typically, it’s pointed out as 12 weeks or 3 months. So, among the given options, the correct one is 3 months, which corresponds to answer letter C. I’ll remember to include citations and refer to known guidelines if needed.
