Which of the following is NOT a VORTAC in ZAE?

A VORTAC is a navigation aid that combines VOR, TACAN, and DME signals and is listed within a specific airspace region. For ZAE, you want nav aids located in the ZAE area (the southern Africa region). Greenville is not in that region—it’s in Mississippi, United States. Because of its geographic location, Greenville (GLH) is outside ZAE and therefore is the one that is NOT a VORTAC in ZAE. The other names correspond to nav aids that are within the ZAE airspace, which is why they fit as ZAE VORTACs. On charts, you can confirm by checking the coordinates or FIR boundaries to see where each VORTAC sits.
