When monitoring the execution quality of risk-related plans and processes, which of the following would be a useful metric to track and record?

The number of risks in the project register is a quantity metric measuring risk inventory size, not the quality or fidelity of risk management process execution.

The degree of variation from the baseline measures project performance against scope, schedule, or cost baselines and does not specifically assess the quality of risk management process execution.

The number of levels in the risk breakdown structure is a structural attribute of the RBS used during planning, not a runtime metric for monitoring process execution quality.

The degree of variation from the risk response strategy is a direct quality metric that reveals whether planned risk responses are being executed correctly and consistently, making it an effective indicator of process adherence and execution quality relative to what was planned in the risk management plan.
