If a host is monitored, and there are seven TCP packets captured: {S1, S2, S3, S4, S5, S6, E1}, where Si represents ith Send packet, and Ej represent jth Echo packet. E1 here acknowledges and echoes all the six Send packets cumulatively. Based on the First-Match Algorithm, which of the following is correct?

Question 6 options:

E1 matches with S1

E1 matches with S2

E1 matches with S3

E1 matches with S6
