A customer needs to cancel all appointments within a specific area due to climate changes...

The Dispatcher Console Map is the most efficient tool for geographic mass actions.

Option A is correct.Salesforce Field Service allows dispatchers to draw customMap Polygonsdirectly on the Gantt map. Once a polygon is drawn around the affected bushfire area, the dispatcher can right-click the polygon (or use the actions menu) to performMass Actionson all Service Appointments contained within that shape. "Unschedule," "Cancel," or "Flag" are standard bulk actions available in this context.

Option B (Reports/Data Loader) is too slow for an emergency response.

Option C (Optimization) would just move the appointments to later times, not cancel/unschedule them.

Option D (List View) is difficult because defining a "bushfire area" using text filters (City, Zip) is often inaccurate compared to drawing the precise boundary on a map.
