Biometrics is the technology used to identify or verify a person's identity by analyzing unique physical or behavioral characteristics. Common biometric methods include fingerprint recognition, retinal scanning, iris recognition, facial recognition, voice recognition, and hand geometry. Since these characteristics are unique to every individual, biometric systems provide a highly secure method of authentication. Therefore, Option A (Biometrics) is the correct answer.
Biometric authentication is widely used in modern security systems because it is more reliable than traditional passwords or PINs. Today, smartphones, laptops, banks, airports, government organizations, and access control systems use biometric technology to verify the identity of users before granting access. Since biometric traits are difficult to copy or steal, they provide an additional layer of security.
