Question

how do viruses reproduce?
by invading dead cells
by exposure to light and water
by invading living cells
by osmosis

Explanation:

Viruses are non - living entities that require a host cell to reproduce. They invade living cells and hijack the cellular machinery to replicate themselves. Dead cells cannot support viral replication as they lack the necessary metabolic functions. Exposure to light and water is not relevant to viral reproduction, and osmosis is a process related to the movement of water across a semi - permeable membrane, not viral reproduction.

Answer:

C. By invading living cells
