Which of the following is correct for Default update behaviour?

The "Default" update behavior for Android apps is designed to optimize user experience and data usage. Apps will update automatically when the device meets three conditions: it's connected to a Wi-Fi network (to avoid using cellular data), it's charging (to ensure sufficient power for the update process), and it's not actively being used (to prevent interruptions during user interaction). The other options include conditions that are either not standard default behaviors (like "at night time" or "at home based on GPS location") or imply manual intervention ("User manually press update"), which contradicts the automatic nature of default updates.
