Final Answer : B, Explanation :  The empirical rule states that approximately 68% of cases fall within 1 standard deviation from the mean, 95% fall within 2 standard deviations from the mean, and 99.7% fall within 3 standard deviations from the mean. Therefore, the best choice is B, as 95 percent of cases fall within 2 standard deviations from the mean.
