Choice D is correct because it accurately identifies both limitations of using the range as a measure of variation. Only considering the two extreme scores in a distribution can be misleading, especially if there are outliers that significantly impact the range. Additionally, the range can be distorted by a single unusually high or low score in the distribution, which may not be representative of the rest of the data. Choices A, B, and C all describe limitations or issues with the range, but only D includes both major drawbacks.
