Show answer & explanation
Correct answer: A
The correct matching is A–IV, B–III, C–II, D–I. Wireless mice typically operate using radio waves (or Bluetooth). Optical mice use infrared light sensors to track movement. Liquid Crystal Displays are output devices used for visual information. Optical Character Readers (OCR) are used to read text like car number plates.
