Correct option is B
Logic: To determine the number of people who rely on both solar energy and coal energy, we need to identify the sum of the numbers that appear in the area of the figure representing solar energy and coal energy. The highlighted part in the figure represents the people who rely on both solar energy and coal energy.
So, the number of people who rely on both solar energy and coal energy = 28 + 12 = 40
Therefore, there are 40 people who rely on both solar energy and coal energy.
Thus, the correct answer is (b).
