Explanation

MSDP (Multicast Source Discovery Protocol) is specifically designed to interconnect multiple, independent PIM-SM (Protocol Independent Multicast – Sparse Mode) domains. Each domain has its own Rendezvous Point (RP), and MSDP allows RPs in different domains to learn about active multicast sources in each other's domains by exchanging Source-Active (SA) messages. This enables receivers in one PIM-SM domain to join sources in another, greatly improving scalability and management of multiple multicast domains. PIM-DM (A) is a dense-mode protocol that floods and prunes within a single domain. PIM-SP (B) is not a standard protocol acronym. IGMP (C) operates at the host-to-router level for group membership, not between domains.
