Which of the following is a reason to use shielded wire?

Shielded wire consists of an inner conductor surrounded by a metallic braid or foil shield. This grounded shield acts as a barrier, preventing outside electromagnetic interference (EMI) or stray radio frequency (RF) signals from coupling onto the inner wire and causing noise in your system. Equally important, the shield prevents the signals traveling inside the inner conductor from radiating outward and causing interference to other nearby electronic devices. This makes shielded wire essential for sensitive audio, microphone, or data connections. The other options are incorrect because shielding does not inherently decrease resistance or increase current-carrying capability; those factors are determined purely by the wire's physical thickness (gauge).
