A detailed contingency plan is most helpful because it outlines actions when obstacles arise.

• A. A cheerful briefing
• B. A status report
• C. Detailed contingency plan
• D. A debt schedule

Answer: (C)

The main concept being tested is planning for disruptions by outlining actions when obstacles arise. A detailed contingency plan provides predefined steps, roles, resources, and decision points to follow as soon as a problem is detected, which helps maintain progress, safety, and mission integrity even when things don’t go as expected.

A cheerful briefing focuses on morale, not on how to respond to issues. A status report shows current conditions but doesn’t guide what to do next when obstacles appear. A debt schedule is about finances, not operational responses to disruptions. That's why a detailed contingency plan is the best choice—it directly equips you to respond quickly and coherently when challenges surface.
