According to the figure, the majority of IQ scores fall between 70 and 130, which represents roughly 95% of the population. Therefore, option D is the best choice. Options A and B are too extreme, and option C is too high, as it suggests that 75% of the population has an IQ score above 130, which is not supported by the figure.
