Detailed explanation-1: -So, the answer is B. Virus, that reproduce inside a host cell. Note: Viruses replicate by lytic and lysogenic cycle.
Detailed explanation-2: -A lysogenic virus remains inactive for a period of time. In the lysogenic cycle, the viral DNA gets integrated with the host’s DNA and gets copied when the host cell replicates.
Detailed explanation-3: -Viruses reproduce only inside the cells of the host organism. It utilises its host cell’s machinery to make copies of themselves.
Detailed explanation-4: -They do not possess ribosomes and cannot independently form proteins from molecules of messenger RNA. Because of these limitations, viruses can replicate only within a living host cell. Therefore, viruses are obligate intracellular parasites.
