D Correct answer
Explanation

DLCI (Data Link Connection Identifier) is the identifier used in Frame Relay to determine which virtual circuit a frame belongs to. Each DLCI identifies a specific PVC (Permanent Virtual Circuit) through the Frame Relay network. DTE and DCE are devices, and LMI is a signaling protocol, but only DLCI identifies the channel.
