Can anyone could provide a better explanation to the answer of the question below ?
As you can see I selected B and C as opposed to B and E
Option C. seems correct in as much as ACK 3100 = I ACKnowledge the last sequence of 2600, send 3100 next
Host 1 sends three consecutive TCP segments to Host 2, with sequence numbers 1600, 2100, and 2600, respectively. All three segments have a source port of 80 and a destination port of 1600. Assuming that Host 2 responds to acknowledge successful receipt of all three segments, which of the following are true ?
Select the best 2 answers
A. The segment that is sent from Host 2 to Host 1 has an acknowledgment field set to 3 more than the acknowledgment field of the previous segment that Host 2 had sent to Host 1. B. The segment that is from Host 2 to Host 1 has a destination port of 80.
C. The segment that is sent from Host 2 to Host 1 has an acknowledgment field of 3100
D. The segment that is sent from Host 2 to Host 1 has a source port of 80 E. The segment that is sent from Host 2 to Host 1 has a acknowledgment field larger than 2600
The Answers were B and E, I picked B and C
Each TCP segment might be a different length. Nothing in the question states the number of bytes of data in the third packet, so it is impossible to know which number Host 2’s field has been set.

Yeah your right for some reason I was thinking SYN instead of SEQ and that it was the inital connection. I plan on doing some re-reading on the subject because frankly it's been a while.
Anyways I would avoid opening any power points on the subject I got a nasty virus that I had to fix. Sure it only took me 2 hours to fix but thats because I knew what to do right away and I've dealt with viruses before.
locked out task manager
locked out msconfig
set Chrome and Internet explorer to proxy the loopback address
added some files and attempted to read my hard drive for information
Also some other stuff that got stopped by me pulling the ethernet cord and rebooting to safemode and running AV's
Fortunately any useful files I always keep on a thumb drive which is only attached physically when I need it to be and I noticed the issue right away and pulled the ethernet cord and did a restart really quick.-
