The correct answer is C. Mumps is a disease caused by a virus.
A fungus is a eukaryotic organism that is not a plant or animal. Fungi are typically multicellular and have a cell wall made of chitin. They reproduce by spores and can be found in a variety of habitats, including soil, water, and on plants.
A bacterium is a prokaryotic organism that is typically unicellular. Bacteria have a cell wall made of peptidoglycan and reproduce by binary fission. They can be found in a variety of habitats, including soil, water, and on plants and animals.
A virus is a non-cellular infectious agent that replicates only inside the living cells of other organisms. Viruses are typically much smaller than bacteria and are not visible with a light microscope. They are made up of a nucleic acid core (either DNA or RNA) surrounded by a protein coat. Viruses can cause a variety of diseases in humans, animals, and plants.
Mumps is a contagious disease caused by a virus. The virus is spread through contact with saliva or mucus from an infected person. Symptoms of mumps include fever, headache, muscle aches, and swelling of the salivary glands. Mumps can be prevented by vaccination.
