You are the lead network designer hired by Service Provider XYZ to deploy CoS functionality on the core MPLS network (P routers).

Service Provider XYZ has these design requirements:

- Queues are numbered 0-3, where 0 is the default queue.
- Three queues have one treatment.

How would you design your solution to map the DSCP value properly so that the traffic is assigned to the respective queues in the Service Provider XYZ MPLS core network?

A. Classify traffic according to DSCP value into appropriate P router queues.
B. Map the appropriate DSCP value into the EXP field based on the number of queues in the MPLS P routers.
C. Map the appropriate DSCP value into the EXP field based on the number of queues in the MPLS PE routers.
