To decrypt a smartphone or tablet when you want to use it, the correct choice is A PIN or passcode.

When a device is locked, it is encrypted to protect the data stored on it. To access or decrypt the device, the user must input the correct PIN, passcode, or password that was set up during the configuration of the device. This security measure is essential to ensure that only authorized users can access the personal information and applications on the device.

Antivirus software, a secure network connection, and a VPN do not serve the purpose of unlocking an encrypted device; they are related to security and safe internet use but do not decrypt a device for access.
