Option 1: The order of the Mobile Country Code (MCC) and Mobile Network Code (MNC)
Option 2: The coding scheme as per Core network protocols
Option 3: The position of the Access Technology in the list, with the first having the highest priority
Option 4: The specific values assigned to the MCC and MNC for HPLMN identification
Explanation: According to the specification, the Access Technology Contents within EFHPLMNwAcT are listed in priority order. This implies that the position of each Access Technology within the list directly influences the MS's search priority for its HPLMN, with the first technology in the list being the highest priority. This is crucial for efficient network selection and connectivity in telecom networks.
