Question $43$:

Hosts A and B are communicating over a TCP connection. Host B has already received from Host A all bytes up through byte $100.$ Suppose Host A then sends two more segments to Host B back$-$to$-$back. The first segment contains $34$ bytes of application data, while the second one holds $65$ bytes of application data. The source port number is $203,$ and the destination port number is $101.$ Host B sends an acknowledgment whenever it receives a segment from Host A$.$

For the segment sent from Host A to Host B with $65$ bytes of data, what is the sequence number?

Options:

A$)165$

B$)135$

C$)199$

D$)101$
