Which two solutions can prevent the multicast traffic from being affected by the RPF check failure due to the MPLS TE tunnel deployment?

Refer to the exhibit.

IPTV video clients are connected to R6. Unicast and multicast traffic flows from R1 to R6. The OSPF cost of the R1-R2-R3-R6 path is lower than the R1-R5-R4-R3-R6 path

To enable load sharing and fast reroute, the design team decided to implement MPLS TE tunnels between R1 and R3 using the forwarding adjacency feature. After the MPLS TE tunnels are deployed, the multicast traffic stops working

While trouble shooting the issue, the operations engineer noticed that the OSPF route to the multicast source is learned via the MPLS TE tunnel, which causes the RPF check to fail.

Which two solutions can prevent the multicast traffic from being affected by the RPF check failure due to the MPLS TE tunnel deployment? (Choose two)
A . Replace forwarding adjacency by autoroute announce and enable the multicast-intact feature
B . Enable PIM on the MPLS TE tunnel on both headend routers
C . Enable the Multitopology routing feature
D . Enable a new routing protocol, such as another OSPF process, on the core-facing links
E . create a static mroute on R3 with the RPF pointing to the MPLS TE tunnel
