. A schematic arrangement for transmitting a message signal \( (20 \mathrm{~Hz} \) to \( 20 \mathrm{kHz} \) ) is given in figure

Which of the following statement(s) is/are correct?
I. The message signal is in the AM range and cannot be transmitted beyond some distances as it possess small energy.
II. An Amplitude Modulation (AM) signal does not possess enough energy to travel an appreciable distance from the antenna.
III. The heights of the antennas required are so large that is impossible to build them.
- (a) Only I
(b) I and II
(c) I and III
(d) All of the above
