Concept:The main idea is that the 1946 Richards Constitution failed to accommodate Nigeria's ethnic diversity, which displeased nationalists.
Explanation:The Richards Constitution was introduced in 1946 by Governor Sir Arthur Richards.
It divided Nigeria into three regions: the Northern, Western, and Eastern Regions.
Nigerian nationalists criticized this new structure for grouping many distinct ethnic communities together.
As a result, minority ethnic groups were placed under the control of the larger Hausa-Fulani, Yoruba, and Igbo groups.
This meant that the constitution did not properly recognize the diversity of ethnic groups in Nigeria.
Nationalists also protested that the constitution was imposed without consulting Nigerians.
They viewed it as a way for the British to extend indirect rule rather than prepare Nigeria for self-government.
Because of these defects, the constitution was widely rejected by nationalist leaders.
Answer:Option A: It failed to recognize the diversity of ethnic groups in Nigeria.
