proto_state=01: Typically indicates one-way ICMP traffic or a partially established TCP session.

proto_state=10: Indicates an established TCP session, where the session has completed the three-way handshake and both sides can send and receive data.

proto_state=11: Often indicates a fully established and active bidirectional session.

Explanation of correct answer:

proto_state=10 is the correct indication for an established TCP session as it signifies that the session is fully established and active.

Hold up, I'm pretty sure option D is the answer. proto_state=01 means one-way ICMP traffic, not an established TCP session.
