The correct answer is: B. Cable
A cable is a flexible strand or bundle of conductors used to transmit electrical signals. It is typically made of metal, but can also be made of other materials such as glass or plastic. Cables are used in a variety of applications, including power transmission, data communication, and audio and video transmission.
A wire is a single conductor, typically made of metal. It is used to transmit electrical signals or power. Wires are typically smaller than cables and are often used in applications where flexibility is important.
A bus is a data transmission path that is shared by multiple devices. It is typically used in computer systems to connect the CPU, memory, and other devices.
A line driver is a device that amplifies a signal so that it can be transmitted over a long distance. It is typically used in telecommunications applications.
A modem is a device that converts digital signals to analog signals and vice versa. It is used to connect computers to telephone lines.
In the case of a computer monitor, the monitor is connected to the computer by a cable. The cable typically carries a video signal, which is used to display the image on the monitor.
