Best answer
The correct answer is (a) True

For explanation: True, the greater the frequency shift the further the distance traveled. Such altimeters function by interpreting the time taken by a radio signal, to reflect from the surface of earth back to the aircraft. This information is then used to calculate the altitude of the aircraft.
