Concept:Industrial concentration is the clustering of industries in one area due to favourable locational factors.
Explanation:Industries in Western Nigeria concentrate where raw materials are available and where there is easy access to import and export ports.
A good road network also supports industrial concentration by reducing transport cost and connecting industries to markets.
The creativity of people is a social or human quality, not a standard economic locational factor.
It does not directly attract or keep industries in a particular area.
Therefore, the factor that does not favour industrial concentration among these options is creativity of people in the area.
Answer:C. Creativity of people in the area.
