D Correct answer
Explanation

By default, Cisco switches allow all VLANs (1-4094) across a trunk port. The default trunk configuration does not restrict VLAN traffic unless explicitly configured with the switchport trunk allowed vlan command. This allows all VLANs, including the extended range VLANs, to traverse the trunk link.
