Concept:Britain governed Nigeria through an administrative system that used local rulers to secure cheap labour and natural resources for British benefit. That system is known as Indirect Rule.
Explanation:The colonial policy implemented by Britain in Nigeria was Indirect Rule.
Lord Lugard, the first Governor-General of Nigeria, formally introduced and popularised this system.
Under Indirect Rule, traditional rulers such as chiefs and emirs were allowed to rule their own people.
However, they had to obey British laws and carry out orders from British officials.
These traditional authorities collected taxes, kept order, and supplied labour for public works.
Britain therefore made use of this arrangement to extract resources such as cash crops and minerals from Nigeria at very little cost.
The system equally made cheap labour available for British trading companies and colonial projects in Nigeria.
Assimilation and Association were French colonial policies, not British ones.
Exploitation only describes the aim of colonialism, not the specific policy Britain adopted in Nigeria.
Answer:The correct answer is B. Indirect rule.
