Correct answer: D. Viruses use the host ribosomes for their own requirements.
- A. Viruses have their own ribosomes for protein formation.
- B. New viral ribosomes are formed after viral DNA enters the cell.
- C. Viruses do not need ribosomes for protein formation.
- D. Viruses use the host ribosomes for their own requirements.
Explanation
Viruses are nonliving outside the host cell. When they enter the host cell they use the machinery of the host cell for their replication. This includes the host ribosome as well. Therefore, Option D is correct.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
