Correct answer: C. Virus

  • A. Bacteria
  • B. Fungi
  • C. Virus
  • D. Malaria

Explanation

Option A: Bacteria are single-celled organisms that can cause disease. They are not derived from the Latin word venemus. The word bacteria comes from the Greek word bakterion, which means "small staff". Otion B: Fungi are multicellular organisms that can cause disease. They are not derived from the Latin word venemus. The word fungi comes from the Latin word fungus, which means "mushroom". Option C: The Latin word venume is the root of the English word venom, which is a poisonous substance produced by some animals, such as snakes, spiders, and scorpions. The Latin word virus also comes from venume, and it refers to a small, infectious agent that can cause disease. The word virus was first used in English in the 16th century. It was borrowed from the Latin word virus, which originally meant "poison" or "venom". The modern meaning of virus as a small, infectious agent was not established until the 20th century. Option D: Malaria is a disease caused by a parasite. The parasite is not derived from the Latin word venemus. The word malaria comes from the Italian word mala aria, which means "bad air".

About Viruses

Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
