Answer: c.)

Explanation:

The bit SYN is used in order to synchronize segment numbers in the sender and receiving processes in hosts that are trying to start a data transmitting session between them.

It is initiated by the sending end, that set this bit to " 1", in the TCP header, starting which is known as a "3-way handshake process".

The bit SYN is not used in order to close a connection, the FIN bit is used for this purpose.

If one process set the FIN bit to "1", this means that it has no more data to send.
