A.
Information will be carried in the RSTP BPDUs.

B.
It will be propagated in VTP updates.

C.
Information stored in the Forwarding Information Base and the switch will reply on query.

Explanation:

Recall that the whole idea behind MST is the capability to map multiple VLANs to a smaller number
of STP instances. Inside a region, the actual MST instances (MSTIs) exist alongside the IST. Cisco
supports a maximum of 16 MSTIs in each region. IST always exists as MSTI number 0, leaving
MSTI 1 through 15 available for use. MST must be manually configured on the all switch belongs to same MST region.
