Answer: A, B, C, D - Disabling the iOS Simple Passcode allows a user to use all of the above passcodes.

Key Takeaway:
The simple passcode feature automatically limits the passcode, which locks the iOS device, to 4 numeric characters. This is easy-to-use, but not good for security. Therefore, turn off this feature, and you can use the entire alphanumeric keyboard-which means any of the above passwords are correct.
