MCQ on Virology: Hepatitis and related Viruses

In this blog, I have posted few multiple choice questions regarding Hepatitis Virus properties, lab diagnosis, vaccine etc. Some of the below posted questions are simle to solve if you applied simple logic as you can find right answer by excluding wrong answers, even if you dont know the right answer, but if you know background information required to solve those questions. But some questions are quiet tricky and you are likely to be prey, by choosing the option, which were provided to entice you to click and trap.

I am not posting right answers of those questions right now, because it kills your creativity and your reading habit, just give a try. If any confusion you can ask me later.
