Option 4 : PCM

PAM (Pulse Amplitude Modulation): In analog modulation, if the amplitude of a pulse or duration of a pulse is varied according to the instantaneous values of the baseband modulating signal, then such a technique is called as Pulse Amplitude Modulation (PAM). This is similar to AM modulation in which the carrier amplitude varies according to the modulating signal.

PCM (Pulse Code Modulation): It is a technique by which an analog signal gets converted into digital form to have signal transmission through a digital network. ∴ This belongs to a digital modulation scheme.
