A network engineer is analyzing a packet capture from a host that received data from a web server. The engineer sees the raw Ethernet frame, then the IP packet, then the TCP segment, and finally the HTTP data. The engineer needs to explain to a junior technician the exact order in which the headers were removed on the receiving host. Which sequence correctly describes the de-encapsulation process?

TCP header removed first, then IP header, then Ethernet header

IP header removed first, then Ethernet header, then TCP header

All headers are removed simultaneously

Ethernet header removed first, then IP header, then TCP header
