The correct option is C) Viruses can synthesize their food through photosynthesis.

Viruses are acellular entities that lack the metabolic machinery necessary for processes like photosynthesis or self-synthesis of food. They are obligate intracellular parasites.

Viruses require a host cell to reproduce because they lack the necessary enzymes and ribosomes. They hijack the host cell’s machinery to replicate. Outside a host cell, a virus particle is essentially an inert complex of genetic material and protein, behaving like a chemical substance. They obtain energy and building blocks from the host cell, not through photosynthesis or any independent metabolic activity.
