Right answer is (a) slightly shorter than a half wavelength

The best explanation: The half wave dipole antenna is also known as Hertz antenna. It consists of two straight collinear conductors of equal length separated by a small feeding gap. The length of half wave dipole antenna is slightly shorter than half wavelength. It’s the simplest form of an antenna.
