A1, 2, 4, 3
B2, 3, 1, 4
C4, 1, 3, 2
D3, 2, 4, 1 ✓ Correct
Correct answer: (D) 3, 2, 4, 1 — The correct order is biometric, OMR, RFID, smart cards, so the answer is 3, 2, 4, 1.
Explanation
★The correct order is biometric, OMR, RFID, smart cards, so the answer is 3, 2, 4, 1.
★Fingerprints or retina scans identify a person by their body, so the first blank is biometric.
★A pencil-filled form read by a machine is optical mark recognition, so the second blank is OMR.
★A worn tag with microchips and radio signals is RFID, so the third blank is RFID.
★Plastic cards with a swipeable chip are smart cards, so the fourth blank is smart cards.
★So the ordered terms are biometric, OMR, RFID, smart cards.
★That is the order 3, 2, 4, 1.
