A)have a separate class interval for each observation to get the most informative plot.
B)make sure the heights of the bars exceed the widths of the class intervals,so that the bars are true rectangles.

It is important to label the vertical axis so the reader can understand the counts or percentages in each class interval. The other options are not necessarily true. It is not always necessary to have a separate class interval for each observation, as grouping data can also be informative. The heights of the bars do not necessarily need to exceed the widths of the class intervals, and the location of the mean and median do not necessarily determine the type of skewness.
