1.Option B
Explanation:
FIN_WAIT_2 appears to happen when the server has a active connection with a customer and needs to close down the TCP connection (presumably in light of a typical application layer "exit").The server sends the customer a packet with a "FIN" bit set.At this point, the server is in FIN_WAIT_1 state.The customer gets the FIN bundle and goes into CLOSE_WAIT state, and sends an affirmation packet back to the server.
At the point when the server gets that packet, it goes into FIN_WAIT_2 state.From the server's viewpoint, the connection is presently shut, and the server can't send any more data.However, under the TCP convention, the customer needs to close down additionally by sending a FIN bundle, which the server TCP execution should ACK.The server should close after a timeframe characterized by the Maximum Segment Lifetime (MSL).
