Question: What happens when a toolkit applet attempts to issue a `TIMER MANAGEMENT` proactive command using an unallocated timer identifier, according to the SIM Toolkit Framework's conformance requirements?
Option 1: The SIM Toolkit Framework silently ignores the command and continues executing other applet functions.
Option 2: The SIM Toolkit Framework throws an exception to prevent the command's execution.
Option 3: The SIM Toolkit Framework allocates a new timer identifier to the applet before executing the command.
Option 4: The SIM Toolkit Framework pauses all applet executions until the timer identifier is properly allocated.
Explanation: This ensures the framework maintains control and prevents unauthorized or potentially disruptive actions by the applets, as it throws an exception when encountering an unallocated timer identifier for a `TIMER MANAGEMENT` command.
