B.)nucleic acid
C.)protein capsid
D.)mitochondrion

Answer 1

(B) nucleic acid,,,,,,,,,,

Answer 2

Answer: The correct answer is B) Nucleic acid.

Virus is an infectious particle which consists of nucleic acid ( DNA or RNA) and a protein coat called capsid. It requires host organism for making its copies. This is because it does not contain the essential proteins required for the replication of its genetic material. Hence, it uses machinery of host organism for reproduction.

Nucleic acid is injected into the host organism once the virus attaches itself to the host cell. After its entry, it performs replication and assembly which is finally followed by the release of the new viral particles outside the host.
