• B. There are two nuclei, a micronucleus and a macronucleus
• C. There are two locomotory organelles, a flagellum and an undulating membrane
• D. Tse-Tse fly has no role to play in life cycle

Answer 1

The correct option is C There are two locomotory organelles, a flagellum and an undulating membrane

• Trypanosoma gambiense reproduces asexually by longitudinal binary fission.
  
• As shown in the figure, there is only one nucleus in Trypanosoma.
• Trypanosomes move actively and progress by the movement of the undulating membrane and the free flagellum.
  
• Trypanosomiasis is transmitted to man and animals by a blood-sucking insect, the tsetse fly.
  

So the correct answer is option C.
