Which type of area search expands in concentric circles from a central point?

• A. Concentric circle
• B. Grid search
• C. Strip search
• D. Random search

Answer: (A)

Expanding outward in concentric circles from a central point is the concentric circle search pattern. It starts at the central location, often the last known point of the missing person, and proceeds in successive rings that grow larger with each pass. This approach quickly covers areas close to the center first, ensuring nearby zones are checked thoroughly before moving outward, and it scales as resources allow. In contrast, a grid search sweeps the area with parallel lines for methodical coverage, a strip search follows long continuous strips, and a random search lacks a structured pattern.
