Concept:Each automatic data capture method has a specific working principle: OCR reads printed text, OMR detects marks, RFID uses radio waves, and MICR reads magnetic ink characters.
Explanation:OCR (Optical Character Recognition) scans hard copy and converts it into editable text – matches description III.
OMR (Optical Mark Recognition) senses pre-determined pencil or pen marks on paper – matches description I.
RFID (Radio Frequency Identification) uses tiny electronic devices with a microchip and antenna to read data from a distance – matches description IV.
MICR (Magnetic Ink Character Recognition) reads characters printed in special ink, such as those on bank cheques – matches description II.
Thus, the correct mapping is A-III, B-I, C-IV, D-II.
Answer:The correct answer is option C: A - III, B - I, C - IV, D - II.
