Which network configuration has the smallest minimum triangulation spacing?

Explanation:
In triangulation, how densely the control points are spaced determines the minimum spacing you’ll encounter. A smaller spacing means more points per area, creating a denser network of triangles. This denser arrangement provides better geometric leverage and more redundancy, which helps limit the spread of measurement errors when computing positions. Therefore, the configuration with the smallest spacing—half a kilometer—has the smallest minimum triangulation spacing. The other options (larger spacings like 5, 10, and 15 km) describe progressively sparser networks, which lead to larger minimum spacings.
