Which statement describes a benefit of biometrics?

• A. It is secure
• B. It is expensive to implement and maintain
• C. It needs additional hardware and software
• D. It can be copied easily

Answer: (A)

Biometrics offer stronger authentication by using unique physical or behavioral traits to verify identity. The main benefit is security: traits like fingerprints or iris patterns are linked to a person and aren’t easy to borrow, guess, or share, so it’s much harder for someone to impersonate you compared to passwords or PINs. This makes unauthorized access and credential theft less likely, which is why this option is described as secure. The other statements describe drawbacks or misconceptions rather than benefits. Some systems can be costly to implement and maintain, and they may require additional hardware and software, which are practical trade-offs. The notion that biometrics can be copied easily contradicts the security advantage, since one goal of biometrics is that these traits are hard to replicate.
