In which of the following scanning the phase of the radiator is constant at one frequency?

In which of the following scanning the phase of the radiator is constant at one frequency? Correct Answer Frequency scanning

In frequency scanning, for one frequency all radiators will be in phase. As the frequency is changed then a corresponding phase shift occurs and the beam is scanned. In phase scanning the phase shifters are used and radiators have different phases.
