Solution
The correct option is A Primary
Trypanosomiasis is transmitted to man and animals by a blood-sucking insect vector, the tsetse fly. Tsetse flies become infected when taking a blood meal containing trypomastigotes from an infected human. These parasites undergo asexual reproduction in its gut and transform from procyclic trypomastigotes to epimastigotes. They then move to the salivary glands where they transform into the infective stage to humans. Thus, the correct answer is option A.
