Correct answer: (A) i-b, ii-a, iii-d, iv-c

Explanation

Biometrics identifies a person uniquely through fingerprint, retina or face scans.

OCR reads data directly from a printed hard copy and turns it into computer-readable text.

OMR detects pencil or pen marks placed at predetermined positions on a sheet.

RFID uses tiny microchip-and-antenna tags that can be read wirelessly from up to about five metres.

This pairs biometrics with identity scans, OCR with hard-copy reading, OMR with mark reading and RFID with the tags.

All four are automatic data capture methods that avoid manual keying.
