Which one of the following diagrams visualize the result of the root cause analysis study?
The correct answer is D. Cause-and effect diagrams. Cause-and-effect diagrams, also called Ishikawa or fishbone diagrams, are the standard tool for visualizing root cause analysis findings.

Why each option
Cause-and-effect diagrams, also called Ishikawa or fishbone diagrams, are the standard tool for visualizing root cause analysis findings.
Activity diagrams model the flow of activities or workflows in a process, not the causal relationships behind a problem.
State diagrams represent the states of a system or object over time and are not used to analyze or display root causes.
Tornado diagrams are used in risk or sensitivity analysis to rank variables by their impact, not to visualize root cause relationships.
Cause-and-effect diagrams (Ishikawa/fishbone diagrams) are specifically designed to map potential causes of a problem back to a central effect, making them the primary visual output of a root cause analysis study. They organize causes into categories such as people, process, equipment, and environment, allowing teams to trace contributing factors systematically.
