The transport layer offers services for host-to-host communication of applications. If required, it takes data from the application layer and breaks into smaller pieces. They are given a sequence number so that they can be re-ordered at the receiving end of each segment. The transport layer also deals with error control and flow control.

In option C, VoIP phone contains a unique identifier that the transport layer utilizes to deliver data segments to appropriate destination device over the given network. This unique identifier serves as the “address” that enables data to be sent by way of some transport layer into a proper recipient. The other alternatives outline the role of distinct layers – application layer formats output, presentation has duty as encoding manipulation while session monitors a number connections from various applications. Only option C details the function of transport layer in host-to-host communication with addresses.
