A
Sensor
B
Mouse
C
Remote control
D

Explanation: 

Detailed explanation-1: -TV remote controls work in a similar way but using a type of light called infrared (or IR for short). The remote control has an LED light in it which flashes really quickly to emit a message which is then picked up by the TV. The remote is called the transmitter, and the TV is called the receiver.

Detailed explanation-2: -Infrared remotes can operate TVs and videos only over quite short distances. The infrared LED is quite small and low-powered and the receiver on the TV or video is small too. This is why you generally have to point the remote directly at the appliance you’re trying to control.
