Answer:

Correct option is C.

Datalink

Explanation:

In tcp/ip, a message belonging to the network layer is de-capsulated from a packet at the datalink layer.

Multiplexing data streams, data frame detection, media access, and error control are all handled by the data link layer. In a communication network, it enables reliable point-to-point and point-to-multipoint connections.

Examples of data link protocols:

Ethernet, Point-to-Point Protocol (PPP), HDLC and ADCCP.
