Which of the following is an example of a virus?

Explanation:
Viruses are tiny infectious agents that cannot replicate on their own and must hijack a host cell’s machinery to reproduce. Influenza fits this pattern: it’s a virus with its genetic material enclosed in a protein coat, and it reproduces only inside cells. This is different from the other options: Salmonella is a bacterium, Candida is a fungus (yeast), and Plasmodium is a protozoan parasite that causes malaria. Because viruses rely on host cells, treatments target viral replication or boost the immune response, rather than the antibiotics that work against bacteria.
