B.
Ingress traffic from the host will be tagged with the CoS value of 5.

Explanation:
The “Switchport voice vlan vlan-id dot1q” command enables voice VLAN on switch port and
associated VLAN.
The “mls qos trust cos” command enables QoS (Quality of Services ) based on COS (Class
of service)
The “switchport priority cos <priority>” value sets the priority values to frame coming from PC
to switch port. Since this has not been explicitly configured, the default CoS value of the port
will be used.
