Correct option is B
The quality control technique most effective for analyzing the factors contributing to defects in a process is the Ishikawa diagram, also known as the cause-and-effect diagram or fishbone diagram. This tool visually organizes potential causes of a problem into categories such as man, machine, method, material, measurement, and environment, helping teams systematically identify the root causes of defects. Other tools like scatter diagrams, control charts, and Pareto charts are useful for analyzing relationships, monitoring variation, or prioritizing issues, but the Ishikawa diagram specifically focuses on tracing defects back to their causes.
