Is the following description of the BSR/RP mechanism correct?

In PIM-SM's BSR/RP mechanism, multiple C-BSRs may exist but only one is elected as BSR (A). C-RPs unicast their advertisements toward the BSR/C-BSRs, and C-BSRs collect this C-RP information (C). The elected BSR encapsulates the RP-Set and BSR information into Bootstrap messages, which are flooded hop-by-hop to every router in the domain (B). All three statements accurately reflect the standard operation of the dynamic RP election process described in Huawei's multicast configuration guides and RFC 5059.

(No options are incorrect — A, B, and C are all valid descriptions of the BSR/RP mechanism.) References
