Question: What assumption should a mobile station make when receiving the Local Time Zone Information Element from the network?
Option 1: The time zone applies to the entire country.
Option 2: The time zone is only applicable for a specific service.
Option 3: The time zone applies to the routing area of the cell the MS is currently in.
Option 4: The time zone is not adjusted for Daylight Saving Time.
Explanation: When the network sends the Local Time Zone Information Element, the mobile station should assume that this time zone is applicable to its current location, specifically the routing area of the cell it is in. This ensures that the mobile station can accurately adjust its local time according to the network's indication, including any adjustments for Daylight Saving Time.
