Detailed explanation-1: -All viruses are obligate parasites because they lack metabolic mechanisms of their own to make energy or to synthesize proteins. That’s why they depend on host cells to carry out these important functions. So this is the correct option.
Detailed explanation-2: -Viruses are intracellular obligate parasites. Ther are incapable of multiplication or survival outside a living host cell. So, they form the connecting link between the living and the dead.
Detailed explanation-3: -Parasitic viruses, also known as file viruses, spread by attaching themselves to programs. When you start a program infected with a parasitic virus, the virus code is run. To hide itself, the virus then passes control back to the original program.
Detailed explanation-4: -Bacteria and viruses can live outside of the human body (such as on a countertop) sometimes for many hours or days. But parasites need a living host to survive. Bacteria and parasites can often be killed with antibiotics. But these medicines can’t kill viruses.
