In a skewed distribution, the mean is typically pulled in the direction of the skew. If the data is skewed to the right (positively skewed), the mean will be greater than the median, and if it's skewed to the left (negatively skewed), the mean will be less than the median.
Without the actual image to analyze the placement of points A, B, C, and D, I cannot definitively determine which point represents the mean. However, if the information implies that the data is skewed towards one side, look for the point that is furthest in the direction of the skew relative to the median.
If you have additional context about the skew (whether it is right or left) or positions of the points, please provide that information for a more precise answer.
