Assertion  : Microwave propagation is better than the sky wave propagation.

Reason      :  Microwaves have frequencies 100 to 300 GHz, which have very good directional properties.

(a) If both assertion and reason are true and the reason is the correct explanation of the assertion.

(b) If both assertion and reason are true but reason is not the correct explanation of the assertion.

(c) If assertion is true but reason is false.

(d) If the assertion and reason both are false.
