Answer 1

The correct option is C Session layer

Session layer is not present in TCP /IP Model.

TCP/IP means Transmission Control Protocol and Internet Protocol. It is the network model used in the current Internet architecture as well. These protocols describe the movement of data between the source and destination or the internet.

The session layer provides the mechanism for opening, closing and managing a session between end-user application processes, that is a semi-permanent dialogue. Communication sessions consist of requests and responses that occur between applications. Session-layer services are commonly used in application environments that make use of remote procedure call.
