Explanation

Biometric controls must rely on physical or behavioral characteristics that are unique to each individual and remain relatively stable over time. Height and weight fail both criteria: they are not unique (many people share identical measurements), they change significantly over a person's lifetime due to factors like age, diet, and illness, and they can be easily approximated or falsified. In contrast, iris patterns, fingerprints, and voice are all considered strong biometric identifiers because each person's iris structure and fingerprint ridges are highly unique, and voice patterns carry distinctive frequency and resonance characteristics that are difficult to replicate.
