Allen is an intern at Changing Lives, a child service organization. He is preparing a pie chart to show how the organization's administrative overhead expenditure is lower than the children's service expenditure. To make the chart easy to understand, Allen should:

A) avoid using legends to identify the slices.
B) explode the slices that need to be emphasized.
C) label only those slices that reflect service programs.
D) use 3D-type formatting.

Exploding the slices that need to be emphasized will help draw attention to the lower administrative overhead expenditure and make the chart easy to understand. Avoiding legends may make it difficult to understand which slice represents what, labeling only service program slices may not give a complete picture of the overall expenditure, and using 3D-type formatting may distort the data and make it difficult to accurately compare the slices.
