Question: What is a specific characteristic of the GET RESPONSE command in the context of the Subscriber Identity Module - Mobile Equipment (SIM-ME) interface?
Option 1: Class = '00' with explicit file selection required before execution.
Option 2: Class = 'A0' allowing execution as the first command after SIM activation.
Option 3: Class = 'FF' mandating a secure channel establishment prior to use.
Option 4: Class not defined, dependent on Mobile Equipment (ME) configuration.
Explanation: The correct answer is Option 2 because the GET RESPONSE command has a Class = 'A0', permitting its execution immediately after SIM activation, without requiring an explicit file selection, which streamlines communication between the SIM and Mobile Equipment (ME).
