Question: Upon receiving a Floor Release message from a floor participant interface, what action does the floor control server interface take with regards to a pending Floor Request message from the same participant in the passive floor request queue?
Option 1: Leaves the Floor Request message in the passive floor request queue for further evaluation.
Option 2: Removes the Floor Request message from the passive floor request queue.
Option 3: Sends an additional Floor Release message to all queued participants.
Option 4: Initiates a new Floor Request sequence to the controlling MCPTT function.
Explanation: According to the specified behavior for handling a received Floor Release message, if there is a corresponding Floor Request message from the same floor participant in the passive floor request queue, the floor control server interface must remove this Floor Request message from the queue. This ensures synchronization and proper state management between floor control operations and participant requests.
