Greenwood airport is 10 miles away from which VORTAC?

Think about how navigation aids are placed on a chart and how you measure distance from an airport to a nearby navaid. A VORTAC provides VOR guidance plus DME, so pilots can determine position and distance from the navaid. To answer which VORTAC is about 10 miles from Greenwood, you’d look at the chart to see where each VORTAC sits relative to Greenwood airport. The Sidon VORTAC is the closest among the options to Greenwood, lying roughly ten miles away. The other VORTACs are positioned farther away, so they don’t match the stated distance. If you want to verify, you can check an IFR enroute or terminal chart or use flight planning software to measure the straight‑line distance between Greenwood and each VORTAC.
