Solution

The correct option is A a

Having the range of wavelength from 30 km to 30 cm are known as short wave. These waves are used for radio transmission and for general communication purpose to a longer distance from ionosphere. Ionosphere is the outermost region of atmosphere extending from height of 80 km to 400 km approximately, above the surface of earth. Therefore, both the assertion and reason are true and reason is the correct explanation of assertion.
