Which color identifies main roads, built up areas, and dangerous or restricted areas?

• A. Red
• B. Black
• C. Blue
• D. Green

Answer: (A)

Color coding on maps helps you quickly interpret the layout of an area. Red identifies major roads and built-up areas, so you can see where the primary routes and densely developed zones are. It also commonly signals dangerous or restricted areas, alerting you to exercise caution or follow access rules. By contrast, other colors serve different purposes: blue marks water features, green shows vegetation or wooded areas, and black is used for non-major man-made features and labels. Since red uniquely covers major infrastructure and restricted zones, it best fits all three categories in the question.
