You set up an experiment in which host a blasts a 26 megabyte file to host b through a single tcp tahoe connection over a 1 gigabit/sec ethernet. b transmits no data. neither host uses any ip or tcp options. the maximum ethernet payload size is 1500 bytes. with no options, the ip+tcp headers occupy exactly 40 bytes. this leaves a tcp maximum segment size (mss) of 1,460 bytes, approximately 1/18,000 the size of the file. which of the following statements are true (there is at least one correct answer, but there may be more): a) host b can send tcp acknowledgments to host a even though it has no data to send. b) the size of the flow control window in segments b sends (the window field) cannot increase throughout the duration of the connection. c) the size of the flow control window in segments a sends (the window field) cannot decrease throughout the duration of the connection. d) suppose that the last rtt sample at host a is 10 msec. the current value of the rtt estimate must be greater than or equal to 10 msec. e) if the user temporarily stops or suspends the process receiving the data on host b, host a will eventually stop sending new data until b's receiver process is resumed.
