B. While they do infect host cells, they only do it to reproduce.  C is wrong because they do have genes (RNA), and D is wrong because viruses can be seen under a microscope, just not your average bio lab scope.

It is B. They do infect host cells, like other living organisms do, they do have genes, they have definite structural features.
