How doTCP SYN attacks take advantage ofTCPto prevent new connections from being established to a host under attack？（）

A、A.These attacks send multiple FIN segments forcing TCP connection release.

B、B.These attacks fill up a hosts’ listen queue by failing to ACK partially openedTCPconnections.

C、C.These attacks take advantage of the hosts transmit backoff algorithm by sending jam signals to the host.

D、D.These attacks increment the ISN of each segment by a random number causing constant TCP retransmissions.

E、E.These attacks send TCP RST segments in response toconnection SYN+ACK segments forcing SYN retransmissions.
