Explanation:

Pareto charts are useful for showing the relative importance of different categories by ranking them in descending - order of frequency or impact. Pie charts show the proportion of each category to the whole. In this case, the Pareto chart on the left ranks the job - sources by frequency, making it easier to identify the most important ones. The pie chart just shows the proportion visually but does not rank them.

Answer:

A. The Pareto chart is more effective.
