Answer:

b. They cannot reproduce outside of a host cell.

Explanation:

Viruses are parasitic organisms that need a host in order to thrive and reproduce. This means that they cannot replicate outside of a host cell, but can only do this by parasitizing it. They have to find a host cell in order to continue their life-cycle or else they won't thrive. The word "obligate" means being restricted to a specific mode or function in life. This shows that the virus has a restriction when it comes to reproduction. It cannot reproduce without finding a host cell.
