A
If both assertion and reason are true and reason is the correct explanation of assertion
100%
B
If both assertion and reason are true but reason is not the correct explanation of assertion
0%
C
If assertion is true but reason is false
0%
D
If both assertion and reason are false
0%
Solution:
The sky waves are the radio waves used for very long distance radio communication at medium and high frequencies (i.e., shortwave band). In shorter wavelength, attenuation is very less.
