The middle 95% of a normal distribution falls within approximately 2 standard deviations of the mean. The mean is 200 pounds, and the standard deviation is 25 pounds. To find the minimum weight of the middle 95%, subtract 2 standard deviations from the mean: 200 - 2(25) = 200 - 50 = 150. Since 151 is the closest option, it is the correct answer.
