Question: What is the primary function of the `CatGetCHVStatus` API entry point in a (U)SIM Application Programming Interface (API), as defined by telecom standards?
Option 1: To update the Card Holder Verification (CHV) status on the (U)SIM.
Option 2: To authenticate a user using the provided CHV against stored credentials.
Option 3: To reset the CHV to its default value for enhanced security.
Option 4: To retrieve and return the current CHV status information from the (U)SIM.
Explanation: The correct answer, Option 4, aligns with the telecom domain's understanding of API functions related to (U)SIM management. `CatGetCHVStatus` is designed to fetch and return the current status of the Card Holder Verification (CHV), which is crucial for managing access and security on the (U)SIM. This function does not involve updating, authenticating, or resetting the CHV, as suggested by the other options, but rather focuses on retrieving its status.
