All viruses can reproduce only within living organisms, so they are known as:
Correct answer: C. Obligative Intracellular Parasites
- A. Ectoparasites
- B. Endoparasites
- C. Obligative Intracellular Parasites
- D. Facultative Intracellular Parasites
Explanation
Intracellular obligate parasites depend on the host not only for nutrition but also for reproduction. These organisms infect the host cell and utilize the internal cellular machinery of the host to replicate themselves.

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.
