D) Standard deviation
In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean of the set, while a high standard deviation indicates that the values are spread out over a wider range.
Mean and Median is a measure of central tendency and Quartile measures the spread of values. So Our Answer is Standard deviation, is measure of dispersion.
