Referring to the link shared by DirkBaert. it says vlan-ids must be same in case of CCC. So it should be TCC. Configure the logical unit of the customer edge interface with a VLAN ID: NOTE: The VLAN ID cannot be configured on logical interface unit 0. The logical unit number must be 1 or higher. The same VLAN ID must be used when configuring the customer edge interface on the other PE switch.

The answer is D, from JI2V student guide "You can have different VLAN IDs if you are using TCC encapsulation."

Translational cross-connect (TCC) allows you to forward traffic between a variety of Layer 2 protocols or circuits. It is similar to its predecessor, CCC. However, while CCC requires the same Layer 2 encapsulations on both sides of a router (such as Point-to-Point Protocol [PPP] or Frame Relay-to-Frame Relay), TCC lets you connect different types of Layer 2 protocols interchangeably.

Correct answer should be A. You can swap using vlan-ccc. vlan-tcc is for different layer 2 protocol endpoints.
