Which combination correctly matches the device with its primary function?
OMR – Detecting shaded marks on paper
OMR (Optical Mark Recognition) is correctly matched with detecting shaded marks on paper, such as in answer sheets.
OCR actually recognises printed text (not magnetic ink characters), MICR reads magnetic ink characters (not barcodes), and Barcode Readers capture barcodes (not handwritten text) — making these three combinations incorrect.
Hence, 'OMR – Detecting shaded marks on paper' is the correct answer.
