Explanation

Fingerprint readers (D) are specifically designed to capture impressions of friction ridge skin - the unique raised patterns on fingertip surfaces - making them the precise match for the question's description. Facial recognition devices (A) analyze geometric features of the face, such as the distance between eyes and nose. Iris cameras (B) capture the unique patterns in the colored ring of the eye. Voice recognition voiceprints (C) analyze the acoustic characteristics of a person's speech.

Memory tip: "Friction ridges on fingertips" is the textbook definition of what makes fingerprints unique - if you see "friction ridges," always map that directly to fingerprint readers.
