Solution

The correct option is B Trypanosoma
Trypanosoma is a flagellated protozoan. They possess flagella for locomotion. They are also known as zooflagellates. During their life cycle, trypanosomes multiply and modify into four main types of polymorphic forms which differ from each other in the form of the body and arrangement of organelles. They cause different diseases.
For example:
  1. Trypanosoma gambiense: It is the parasite of sleeping sickness.
  2. Trypanosoma rhodesiense: It causes Rhodesian sleeping sickness.
  3. Trypanosoma cruzi: It causes South American trypanosomiasis (also called Chagas disease).
