Concept:The British merged the separate southern units of Nigeria step by step to make the territory easier to govern.
Explanation:Before
1906, Britain administered the Lagos Colony separately from the Protectorate of Southern Nigeria.
To speed up administration, the British merged these two southern units into a single territory.
The new, larger unit was known as the Protectorate of Southern Nigeria, and it was placed under one administration.
Lagos was no longer governed as an entirely separate administrative unit.
This merger was the first stage of the gradual amalgamation that later produced the whole country of Nigeria.
In
1914, the enlarged Southern Nigeria Protectorate was further joined with the Protectorate of Northern Nigeria to form the Colony and Protectorate of Nigeria.
Therefore, the immediate result of merging Lagos Colony and the Southern Nigeria Protectorate was the Protectorate of Southern Nigeria.
Answer:A. Protectorate of southern Nigeria
