Which of the following antenna types will be most effective as a near vertical incidence skywave (NVIS) antenna for short-skip communications on 40 meters during the day?

Direct answer summary (2023-2027 NCVEC pool)

The official correct answer for G9D01 is A horizontal dipole placed between 1/10 and 1/4 wavelength above the ground.

The key fact is A horizontal dipole placed between 1/10 and 1/4 wavelength above the ground. Match that fact to the exact condition in the question; the other choices describe a different rule, band, component, or operating situation.
