Answer»

Correct OPTION is (a) Multiplexing/ Demultiplexing

The BEST explanation: Transport layer functions are:

–> Multiplexing / DE multiplexing : Normally the transport layer will create distinct network connection for each transport connection REQUIRED by the SESSION layer.

–> Fragmentation and Re assembly: The data accepted by the transport layer from the session layer is SPLIT up into smaller units if needed and then passed to the network layer.
