Viruses can be transmitted through air, water, food, insect bites, and direct skin contact. Once a virus gains entry to the body, it invades a host cell in order to — A. access cellular processes for replication
B. metabolize host proteins and grow
C. synthesize antibodies for defense
D. deactivate the host cell’s defenses

B

I personal will go with B cause viruses attack your immune system then destroy healthy cells then copy it self through out the rest of the body.
