The correct answer is C. 4.
UTP stands for Unshielded Twisted Pair cable, which is commonly used for Ethernet networks. It consists of four pairs of copper wires twisted together in order to reduce electromagnetic interference. Each pair of wires is color-coded and usually terminated with an RJ-45 connector.
UTP cables are commonly categorized by their performance and are classified as either Cat5, Cat5e, Cat6, or Cat7. The number of pairs of copper wires in a UTP cable remains the same regardless of the category.
Each pair of wires in a UTP cable is responsible for transmitting and receiving data, and the wires within each pair are twisted together in order to cancel out any electromagnetic interference that may be present. This allows for more reliable data transmission over longer distances.
In conclusion, a UTP cable has four pairs of copper wire, which are twisted together to reduce interference and improve data transmission.
