Probably yes, but the answer could be no.  All the non-STP switches I've
ever seen do forward BPDUs.

Strictly speaking, 802.1D bridges should never forward frames addressed
to the reserved bridge management MAC addresses.  This would lead both
B & C to believe they were connected to an edge port, which will never
block.
