She ensures that the bars are placed close enough together to make comparison easy. Which of the following corrections to Farah's bar chart will help improve its quality?

A) The labels of the axis should be removed because the title already explains them.
B) The bars should not be placed close to each other.
C) The labels should be placed outside the bars instead of inside.
D) The width of all the bars should be the same.
E) She should use a line graph instead of a bar chart.
