Explanation

Accuracy is the most critical characteristic of a biometric system because the entire purpose of biometrics is to correctly identify or authenticate individuals. An inaccurate system - one with high False Acceptance Rates (letting in impostors) or high False Rejection Rates (blocking legitimate users) - fails at its fundamental security function. Perceived intrusiveness (A) affects user acceptance but not security effectiveness. Storage requirements (B) are an engineering concern. Scalability (D) matters for enterprise deployments but is secondary to whether the system correctly distinguishes authorized from unauthorized users in the first place.
