None of the above

Detailed explanation-1: -A virus is an infectious microbe consisting of a segment of nucleic acid (either DNA or RNA) surrounded by a protein coat. A virus cannot replicate alone; instead, it must infect cells and use components of the host cell to make copies of itself.
Detailed explanation-2: -A virus is an infectious agent that can only replicate within a host organism. Viruses can infect a variety of living organisms, including bacteria, plants, and animals. Viruses are so small that a microscope is necessary to visualize them, and they have a very simple structure.
Detailed explanation-3: -A virus is a non-cellular, infectious entity composed of genetic material and protein that can only invade and reproduce within the living cells of bacteria, plants, and animals. A virus, for example, cannot replicate outside of the host cell.
Detailed explanation-4: -Viruses are small obligate intracellular parasites, which by definition contain either a RNA or DNA genome surrounded by a protective, virus-coded protein coat. Viruses may be viewed as mobile genetic elements, most probably of cellular origin and characterized by a long co-evolution of virus and host.
