Which of the following can aid in the identification of the cause of the majority of the defects on a given project?

Ishikawa diagrams help explore all potential root causes comprehensively but do not inherently rank them by impact or frequency.

Run charts display data over time to identify trends or shifts, not to rank the causes of defects by their majority contribution.

Histograms show the frequency distribution of data and are useful for understanding data spread, but they do not rank causes to identify the majority contributors to defects.

Pareto charts apply the 80/20 rule, illustrating that a small number of causes often account for the majority of problems, thus aiding in prioritizing efforts by highlighting the most impactful defect causes. By ordering categories from most to least frequent, they effectively identify the "vital few" causes responsible for the "trivial many" defects.
