Which distribution type refers to straight or curved lines that originate from a single point of origin and radiate outward in any direction, like the spokes of a wheel?

• A. Radial
• B. Linear
• C. Spiral
• D. Circular

Answer: (A)

Radial pattern describes lines or curves that all start at a single origin and spread outward in multiple directions, like spokes on a wheel. The central point is the source, and everything fans out from there, creating that outward radiating effect. This differs from linear, which runs along a single direction; spiral, where curves wind around the center as they move away; and circular, where lines form closed loops at a constant distance from the center. So radial is the best fit because it specifically captures the idea of emanating from one point and radiating outward.
