We do not transmit low frequency signal to long distances because-
(a) The size of the antenna should be comparable to signal wavelength which is unreal solution for a signal of longer wavelength.
(b) Effective power radiated by a long wavelength baseband signal would be high.
(c) We want to avoid mixing up signals transmitted by different transmitter simultaneously.
(d) Low frequency signal can be sent to long distances by superimposing with a high frequency wave as well.
Therefore, the most suitable option will be :
Option: 1
All statements are true

Option: 2
$\mathrm{(a), (b)}$ and $\mathrm{(c)}$ are true only

Option: 3
$\mathrm{(a), (c)}$ and $\mathrm{(d)}$ are true only

Option: 4
$\mathrm{(b),(c)}$ and $\mathrm{(d)}$ are true only

The size of the antenna should be comparable with the wavelength of the wave.
If the frequency is very small, the wavelength will be large (in km)
So antenna size will be in Km which is not feasible
The correct answer is (3)
