C, D are correct
The election process reviews PRIORITY first: LOWEST priority wins;
If the priority values are the same, brigde address (MAC) are compared: The LOWEST IDENTIFIER wins.

Election procedure –
All the switches in the network declare themselves root bridges and start exchanging their own BPDU. The BPDU with the lowest bridge ID is considered as superior. Now the switch receiving the superior BPDU makes changes in its own BPDU and carries forward to its neighbours. It changes the value of root Bridge ID with its superior BPDU bridge ID. This process goes on until all the switches are satisfied with which bridge has the lowest bridge ID and hence that switch will be declared as the root bridge.
