Question: In a scenario where two or more (U)SIM Toolkit applets are registered to the same event with identical priority levels, what determines the order of their activation?
Option 1: The applet with the highest allocated memory is activated first.
Option 2: The most recently installed applet is activated first.
Option 3: The applet with the lowest priority level setting (non-RFU) is activated first among those with the same priority.
Option 4: Random selection among the applets with the same priority level.
Explanation: According to the specified rules for handling applets with the same priority level registered to the same event, the order of activation is determined by their installation date. This ensures a predictable and manageable sequence, giving precedence to the most recently installed applet.
