Answer: B

Explanation:

Mobile communication is the use of technology that allows users to communicate from different locations without the need for physical mediums such as cables or wires. This is made possible through wireless communication networks that transmit information through the airwaves using radio frequency waves. The wireless signals are captured by mobile devices such as smartphones, tablets, or laptops, which then decode the signals into voice or data information that can be understood by the user. Mobile communication networks have revolutionized the way we communicate, allowing us to stay connected with people from anywhere, anytime.
