Answer: The correct answer is- Viruses are not living.
Viruses are non living, noncellular genetic elements that require a living organism as a host in order to replicate their genome.
They are microscroscopic infectious agents, which are also known as obligate intracellular parasites.
Example- Bacteriophage ( a virus that infects bacteria).
They use the replication machinery of host so as to make more viral copies as they lack any replication machinery.
Thus, first option is the right answer.
