Indirect rule was cheaper and easier for the European powers and, in particular, it required fewer administrators, but had a number of problems. In many cases, European authorities empowered local traditional leaders, as in the case of the monarchy of Uganda, but if no suitable leader could be found (in the traditional Western sense of the term), the Europeans would simply choose local rulers to suit them. This was the case in Kenya and Southern Nigeria, and the new leaders often called "warrant chiefs", were not always supported by the local population.

The answer is option B because there were few British people in Nigeria during the colonial times to rule us so they decided to rule us indirectly
