Concept:Certain indigenous West African cattle breeds possess natural genetic resistance to trypanosomiasis.
Explanation:Trypanosomiasis is a serious livestock disease transmitted by tsetse flies.
Only a few cattle breeds are trypanotolerant, meaning they can survive and produce well in tsetse-infested areas.
The N'dama and Muturu breeds, including the West African shorthorn, are well known for this resistance.
In contrast, zebu breeds like White Fulani, Sokoto Gudali, Red Bororo, and Adamawa are more susceptible.
Thus, the correct pair is N'dama and Muturu.
Answer:C. N'dama and Muturu
