Correct answer: The device does not take an image of the print but a biometric model that then uses an algorithm to create a mathematical, template, A biometric template cannot be copied to another device because it is signed with a device specific key when stored in the, TEE.
Why this is the answer
The device creates a mathematical template of the fingerprint, not an image. This template is a numerical representation, not a scannable picture, making it useless if stolen. Furthermore, this biometric template is stored in the Trusted Execution Environment (TEE) and is signed with a device-specific key. This means the template is cryptographically bound to that particular device and cannot be transferred or used on another device, even if extracted. The incorrect options suggest that biometric data is stored in Google Cloud or on the user's filesystem, which is not accurate for how Android handles fingerprint authentication securely.
