What color wire is associated with the ring of the second pair in a CAT3 cable?

In a CAT3 cable, the wiring follows specific color-coding standards to help identify each pair of wires. The second pair is typically associated with a color scheme that consists of a solid color wire paired with a striped wire. For the ring of the second pair, the correct wire is solid orange.

This wire color convention is essential for maintaining consistency in network installations and ensuring that technicians can easily recognize and connect the appropriate wires during setup and troubleshooting. In the standard wiring configuration, the solid orange wire represents the second pair, while the white-orange striped wire is paired with it. This association helps in avoiding confusion and errors in wiring configurations, which can lead to connectivity issues or signal degradation.

The other choices do not fit the traditional wiring color scheme for the second pair in a CAT3 cable, which is what makes solid orange the correct response in this context.
