Why each option
To support both an IP phone and a PC connected to a single switch port, the port must be configured as an access port to enable both a data VLAN for the PC and a voice VLAN for the phone.
The `switchport mode access` command is the correct foundational configuration for a port connected to an end device like an IP phone with an attached PC, as it allows for the assignment of both a data VLAN and a separate voice VLAN.
`switchport mode trunk` is incorrect because it is used for inter-switch links or links to routers that carry multiple VLANs, not for connecting end devices.
`switchport mode trunk` is incorrect for the same reason as choice B.
Assuming choices A and D are identical in their text content, `switchport mode access` is the correct mode, but other configurations for voice VLAN would typically follow.
