Why the answer is B, and why the others tempt you.
The sea moderates temperatures in coastal areas because water has a high specific heat capacity, meaning it heats up and cools down more slowly than land. This maritime influence reduces temperature extremes in Lagos. Kano, being far inland, experiences the full continental effect with hotter days and cooler nights, giving it a larger annual range.
