And present the following property:

A skewed left distribution is one in which the tail is on the left side. On simple words we have most of the values on the left part of the distribution.
And present the following property:

On a symmetric distribution we satisfy 
For our case we have that
and 
And we can see that
then we can conclude that this distribution is skewed to the right. And the best option would be:
C. The distribution of the value of transaction accounts is a right-skewed distribution.
