Which option uses biometric verification based on hand shape and size?

Explanation:
Hand geometry uses the physical dimensions and shape of the hand—such as palm width, finger lengths, and spacing between fingers—to verify identity. The system captures measurements of these geometric features and compares them to a stored template to confirm the user’s identity. This makes it the biometric method that is based on hand shape and size. Fingerprint authentication relies on ridge patterns on the skin, face recognition analyzes facial features, and a personal USB key is not biometric but a token you possess.
