When a distribution is skewed left, this means that we have outliers in the lower end of the range of values.

These don't influence the median as much, but this affects the mean greatly. Median is more heavily dependent on the frequencies of numbers, not the actual values of those numbers.

Therefore, the mean will be less than the median in a left-skewed distribution.

The only answer choice that fits here is D.

Here is a diagram to help you visualize the expected result:
