The correct answer is (b) Fiber optic cable.
Fiber optic cables are the fastest transmission media because they use light to transmit data. Light travels at the speed of light, which is much faster than electricity. Fiber optic cables are also very thin and flexible, which makes them easy to install and maintain.
UTP cables (Unshielded Twisted Pair) are made up of four pairs of copper wires that are twisted together. They are the most common type of cable used for networking. UTP cables are relatively inexpensive and easy to install, but they are not as fast as fiber optic cables.
Coaxial cables are made up of a central copper wire surrounded by a layer of insulation. This insulation is then surrounded by a metal shield. Coaxial cables are more expensive than UTP cables, but they are also faster and more reliable.
Ethernet cables are a type of UTP cable that is used to connect computers to a local area network (LAN). Ethernet cables are available in a variety of speeds, from 10 Mbps to 10 Gbps.
In conclusion, fiber optic cables are the fastest transmission media because they use light to transmit data. Light travels at the speed of light, which is much faster than electricity. Fiber optic cables are also very thin and flexible, which makes them easy to install and maintain.
