What is the traffic path between workstations on separate switches in a three-tier design?

In a three-tier network design, traffic between workstations on separate switches must traverse all three layers. The path begins at the access layer switch where the source workstation is connected. From there, traffic moves up to its connected distribution layer switch. To reach a different distribution layer, it must then go up to the core layer. The core layer routes the traffic to the destination distribution layer. Finally, the traffic descends to the access layer switch where the destination workstation is connected. Therefore, the full path is access - distribution - core - distribution - access. The other options omit necessary layers or incorrectly sequence them for inter-switch, inter-distribution layer communication.
