You Are the Lead IP/MPLS Network Designer of a Service

You are the lead IP/MPLS network designer of a service provider called XYZ. You are leading a design discussion regarding IPv6 implementation in the XYZ MPLS network, using MPLS 6PE/6VPE techniques. Currently, XYZ provides IPv4 multicast services over an MPLS network by using MVPN, and would like to provide parallel IPv6 multicast services. Which three multicast solutions should be enabled? (Choose three.)

A) native IPv6, only for multicast services
B) MPLS 6PE/6VPE, because it provides IPv6 multicast support by default
C) an overlay model using Layer 2 MPLS tunnels
D) PIM-DM to enable IPv6 multicast in conjunction with MPLS 6PE/6VPE
E) MVPN for IPv6 multicast service
