The answer is the third one (or C): viruses.

Explanation for each option:

  • Protozoans: These are single-celled eukaryotic organisms. They have a cellular structure, including a nucleus and other organelles.
  • Helminths: These are multicellular parasitic worms. They have complex cellular structures and are composed of many cells.
  • Viruses: These are noncellular entities. They consist of genetic material (DNA or RNA) enclosed in a protein coat and sometimes a lipid envelope. They cannot carry out metabolic processes on their own and must infect a host cell to replicate.
  • Bacteria: These are single-celled prokaryotic organisms. They have a cellular structure, including a cell membrane, cytoplasm, and genetic material, although they lack a nucleus.

Summary: Viruses are noncellular microorganisms, unlike protozoans, helminths, and bacteria, which all have cellular structures.
