Explanation

ATM (Asynchronous Transfer Mode) is uniquely identified by its use of fixed 53-byte cells (5-byte header + 48-byte payload). This fixed cell size was deliberately chosen to support time-sensitive traffic like voice and video alongside data, because fixed-size cells allow hardware-based switching at predictable intervals. PPP (A) and Frame Relay (B) use variable-length frames. MPLS (D) uses variable-length labeled packets. X.25 (E) is a legacy packet-switching protocol with variable frames. The '53-byte cell' specification is the definitive identifier for ATM.
