What is Jason trying to accomplish here?

In TCP communications there are 8 flags; FIN, SYN, RST, PSH, ACK, URG, ECE, CWR. These
flags have decimal numbers assigned to them:
FIN = 1
SYN = 2
RST = 4
PSH = 8

ACK = 16
URG = 32
ECE = 64
CWR = 128
Jason is the security administrator of ASPEN Communications. He analyzes some traffic using

Ans: B

Convert the hex values to decimal.

0x02 = 2 (SYN)
0x12 = 18 –> 0x10 — 16 (ACK) / 0x02 — 2 (SYN)
0x10 = 16 –> ACK

tcp.ack==1 (3 way comm is completed with ACK flag)
tcp.len == 0 (ACK flag confirms connection, no data is needed to acknowledge the connection)
