Explanation
A Pareto Chart is correct because it is a bar graph that visually ranks causes or defects from highest to lowest frequency, making it easy to identify which issues have the greatest impact - embodying the 80/20 rule (80% of problems stem from 20% of causes). A Check Sheet (A) is simply a structured form for collecting and tallying data, not for ranking or visualizing causes. A Cause and Effect Diagram (B), also called a fishbone or Ishikawa diagram, maps potential causes of a problem but does not rank them by significance. A Scatter Diagram (C) shows the relationship or correlation between two variables, not a ranking of causes. Memory tip: Think "P for Priority" - a Pareto Chart helps you prioritize which causes to tackle first by ranking them visually from most to least significant.
