Which Ethernet category is designed to reduce cross-talk or noise by twisting the pairs without shielding?

Explanation:
Twisting the conductors in a cable without any shielding reduces cross-talk and noise by canceling interference through the twists. The regular twists cause any unwanted signals that couple into the cable to average out along its length, lowering crosstalk between pairs and making the signal more resilient without needing a shield. This is the hallmark of Unshielded Twisted Pair, which is why it’s widely used for Ethernet under Cat5e and Cat6 standards with RJ45 connectors. Shielded Twisted Pair would add a shielding layer to fight external interference, which isn’t part of the described design, and the other option references the connector type rather than the cable’s shielding characteristics.
