Which multicast rendezvous point redundancy mode is valid for Bidirectional PIM?
Phantom RP is specifically designed for Bidirectional PIM. It provides redundancy by allowing multiple RPs to act as backups, enabling seamless failover in case the primary RP becomes unavailable. This mode is tailored for the bi-directional nature of PIM, where data flows in both directions between sources and receivers.
Answer must be B. Check the Phantom RP section in: https://www.cisco.com/c/en/us/products/collateral/ios-nx-os-software/ip-multicast/whitepaper_c11-508498.html
I reckon Anycast-RP is the correct answer, refer back to your doc, you'll see the Anycast-RP provides RP failover and redundancy.
See page 8 in https://www.cisco.com/c/dam/en/us/products/collateral/ios-nx-os-software/multicast-enterprise/prod_white_paper0900aecd80310db2.pdf. It says "Because multicast source information is no longer available in Bidir, the Anycast/MSDP mechanism used to provide redundancy in sparse-mode is not an option for Bidir". So, correct answer should be B, IMHO

Agree with CHEdot the correct answer is B as the Phantom RP provides dynamic failover in case the primary RP becomes unavailable.
A few hints: MSDP is IPV4 only and used to blamance PIM registrations PIM anaycast RP substitute and extents the role of MSDP to RPs sets and supports IPv6 Phantom RP is specifically for PIM-BiDir, the nature of this model is birectional flowing between source/recievers, and Phantom RPs are just transit points along the flow path (no registration role)
It is Phantom RP of course
