A) Auto-negotiation is not configured on the switch, resulting in the switch not being able to send FLP messages to the workstation, causing the workstation to set its own operating mode to Half-duple
B) Port rate negotiation is negotiated through the initial port sending FLP, and the operating mode is not negotiated through FLP
C) The problem is on the workstation's NIC, mostly due to the aging of the NIC driver on the workstation, which causes the workstation NIC to learn the interface rate and operating mode configured on the switch
