Correct option is A
Wireless mice typically use radio frequency (RF) technology to transmit data between the mouse and the receiver connected to the computer.
They often operate on the 2.4 GHz frequency, which is also used by many Wi-Fi devices.
Radio waves are ideal for this purpose because they can travel long distances and pass through objects like desks and walls.
IR waves (Infrared) are commonly used in remote controls but are not suitable for wireless mice due to their line-of-sight limitations.
Microwaves are used for high-frequency communication like certain types of wireless networking, but not for standard wireless mouse communication.
