P213 159 Biometric access-control systems---those using fingerprints, voiceprints, etc., to regulate admittance to restricted areas—work by degrees of similarity, not by identity. After all, even the same finger will rarely leave exactly identical prints. Such systems can be adjusted to minimize refusals of access to legitimate access-seekers. Such adjustments, however, increase the likelihood of admitting impostors. ---Which of the following conclusions is most strongly supported by the information above? (B) If a biometric access-control system reliable prevents impostors from being admitted, it will sometimes turn away legitimate access-seekers. (C) Biometric access-control systems are appropriate only in situations in which admittance of impostors is less of a problem than is mistaken refusal of access
