when an Ibo-led military council proclaimed a centralized dictatorship

To determine the correct answer regarding the beginning of the Biafran War in Nigeria, we can break down the given options and gather information from historical events.

A. when an Ibo-led military council proclaimed a centralized dictatorship.
This option is incorrect because the Biafran War did not start due to the proclamation of a centralized dictatorship by an Ibo-led military council. The war had other causes.

B. after a countercoup by Nigerian Muslims seized the national government.
This option is not accurate either. A countercoup by Nigerian Muslims seizing the national government did not trigger the beginning of the Biafran War. The conflict was not primarily based on religious differences.

C. after Nigeria was divided into 19 small units.
This option is also incorrect. Nigeria being divided into 19 small units did not directly lead to the commencement of the Biafran War.

D. with the death of the military dictator General Sani Abacha.
This option is false since the Biafran War occurred before the death of General Sani Abacha, who passed away in 1998.

Taking into account the given options and analyzing historical events, none of them accurately describe the actual cause of the Biafran War in Nigeria. The Biafran War began in 1967 after the Eastern Region of Nigeria, primarily inhabited by the Igbo ethnic group, declared secession and established the independent Republic of Biafra. The conflict was a result of political, ethnic, and economic tensions between the Igbo people and the Nigerian government.

Thus, the correct answer is not provided among the given options.
