D Median and interquartile range.
In a distribution that is strongly skewed to the left, the median is a better measure of center than the mean because the mean can be heavily influenced by the skewness. The interquartile range is a more robust measure of spread compared to the range, as it is not affected by extreme values in the tails of the distribution.
