B) The interface subcommand spanning-tree [vlan x] cost y lets an engineer set the switch's STP/RSTP cost on that port, either for all VLANs or for a specific VLAN on that port. Changing those costs then changes the root cost for some switches, which impacts the choice of root ports and designated ports.
