Explanation
PIM Bidirectional (BIDIR-PIM) supports many-to-many application topologies (A), making it ideal for conferencing, collaboration, and similar group communication where multiple sources and receivers exist. It also calculates source trees based on the Rendezvous Point (RP) tree without requiring a separate source registration process (B). Option C is incorrect - registration IS required in PIM-SM, but BIDIR-PIM eliminates the registration process entirely, which is one of its key scalability advantages. The bidirectional shared tree allows traffic to flow both toward and away from the RP without SPT switchover.
