Why each option
Ishikawa diagrams (fishbone diagrams) and Pareto charts are quality control tools used to identify root causes of defects and prioritize issues, respectively.
A Gantt chart is a project schedule management tool used for planning and tracking tasks, not primarily for quality control.
An Ishikawa diagram, also known as a fishbone or cause-and-effect diagram, is a quality control tool used to visually identify and categorize the potential causes of a problem or defect.
Parametric estimating is a cost or duration estimating technique that uses historical data and mathematical algorithms, not a quality control tool.
A probability and impact matrix is a risk management tool used for assessing and prioritizing risks, not for quality control.
A Pareto chart is a quality control tool that displays defects or causes in descending order of frequency or impact, helping to identify the "vital few" problems that need attention.
