P-
What are the possible reasons?

• A. There is no unicast route from RTB to RTA, which causes RTB to fail the RPF check of the source.
• B. The multicast network dynamically elects RP, and RTA fails to check the RPF of BSR.
• C. The RP elected by RTA is not RTB
• D. The RP is statically configured on the multicast network, while the RTA router is not statically configured with the RP
