Answer:
C. A baby can't survive without help, just like a virus needs a host in order to reproduce.
Explanation:
Viruses are not considered living beings because they are obligate intracellular parasites, composed primarily of nucleic acids (DNA, RNA or both, in some cases).
In other words, viruses have no metabolism of their own, so they cannot survive without infecting a host cell, in which the virus sets in and modifies its metabolism in order to produce more viruses.
It is during these processes that viruses cause disease in parasitized organisms.
Your answers would be C and B.
