Answer :
The correct answer is:
D. All
Viruses can replicate in various hosts, including animals, plants, and bacteria. Different viruses have specific host ranges, meaning they can infect and replicate within particular types of organisms. For example, some viruses infect animals like humans, while others target plants or bacteria.
Viruses are considered obligate intracellular parasites, meaning they require a host cell to replicate and reproduce. Once a virus enters a suitable host cell, it hijacks the cellular machinery to make copies of itself. This process allows viruses to replicate and spread within their host organisms.
Therefore, viruses have the capability to replicate in animals, plants, and bacteria, making option D, "All," the correct choice for where viruses can replicate.
