• A. Not True
• B. False
• C. Unknown
• D. True

Answer: (D)

In wildfire management, the color-coded burn status is used to read the terrain. A black area signifies fuel has already burned and is out, while the fire’s edge represents the boundary of ongoing burning. When a line is drawn through the already-burned zone, there is no remaining unburned fuel between that line and the current fire edge, because that section has already been burned to black. That’s why this statement is true: the black line marks a burned area with no unburned material between it and the edge.
