Correct answer & explanation

Elect root bridge using lowest bridge ID

STP first elects a root bridge based on lowest bridge ID. Then each non-root bridge selects one root port (lowest path cost to root). Next, each segment elects a designated port (lowest root path cost, then lowest bridge ID). All other ports become alternate (blocking). Finally, ports transition through blocking, listening, learning, and forwarding states.
