The correct option is B Flagellated protozoan
Sleeping sickness
Sleeping sickness is a parasitic disease that causes symptoms such as joint pain, headache and itching. When the disease gets severe, the person shows symptoms such as confusion and poor coordination. The person suffers from extreme lethargy and unconsciousness. The disease spreads via the bite of the Tsetse fly which carries the pathogen.

Flagellated protozoan
