Concept:The Crown Colony policy was a British system of direct rule that introduced British-style institutions of governance into West African colonies.
Explanation:Under this policy, the British established formal administrative structures modelled on their own systems at home.
One major progressive institution brought in was the Western legal system.
This involved English-style courts, written laws, and legal procedures that replaced or worked alongside traditional customary courts.
These courts introduced concepts like trial by jury, written records, and formal appeals.
Such institutions promoted a uniform legal framework across the colony.
Other options are incorrect because the policy did not create a rigid class system, did not focus on educating traditional rulers, and did not establish military academies.
The main governance reform was therefore the introduction of the Western legal system.
Answer:C. introduction of the Western legal system
