Text Solution
Verified by ExpertsThe correct answer is:
D
An antenna behaves as a resonant circuit when its length is equal to half the wavelength of the transmitted or received electromagnetic wave, or an integral multiple of it:
where 
At these lengths, standing waves are formed on the antenna, resulting in resonance and efficient radiation/reception.
