Final answer:
A Western blot is not a quality or process improvement tool but a biology lab technique for detecting proteins, unlike the Fishbone diagram, Pareto chart, and Six Sigma which are all process improvement tools.
Step-by-step explanation:
All of the following are types of quality and process improvement tools, except c) Western blot. The Fishbone diagram is used for identifying cause and effect relationships in complex processes. The Pareto chart is a bar graph that identifies the most significant factors in a dataset, based on the Pareto principle. Six Sigma is a set of techniques and tools for process improvement. In contrast, a Western blot is a laboratory method used in biology to detect specific proteins in a sample.
