Lagos, Oyo, Ondo et Ogun se trouvent à du pays Nigeria.

Lagos, Oyo, Ondo, and Ogun are all states located in the south-western part of Nigeria. The correct answer is l'ouest (the west).

Nigeria is broadly divided into six geopolitical zones: North-West, North-East, North-Central, South-West, South-East, and South-South. Lagos, Oyo, Ondo, and Ogun all belong to the South-West zone. Since the options do not include "le sud-ouest" specifically, "l'ouest" (the west) is the closest and correct answer.

The other directions are incorrect:

• Le nord (the north) would include states like Kano, Kaduna, and Sokoto.
• Le sud (the south) is too vague and would more accurately describe the South-South zone (e.g., Rivers, Bayelsa, Delta).
• L'est (the east) would refer to states like Enugu, Ebonyi, and Abia in the South-East zone.
