Step 1: RMMM is a risk-handling strategy in software engineering. Each M is a distinct risk activity.
Step 2: The first step is Mitigation, taking action to reduce the chance a risk occurs.
Step 3: The second step is Monitoring, tracking indicators to see whether a risk is becoming real.
Step 4: The third step is Management, deciding what to do when a risk actually happens. So RMMM is Risk Mitigation, Monitoring, and Management.
So the answer is option D.
