Detailed explanation-1: -Answer: Option 2 is the correct answer. Explanation: Twist UTP wires together into some pairs and that causes the magnetic flux effect. This technique is used to protect from cross talk.
Detailed explanation-2: -A standard UTP cable consists of a 100-ohm copper cable made with 2 – 1800 unshielded twisted pairs shielded by an outer jacket. As they have no metallic shield, the cable diameter is reduced but cannot avoid electrical interference. The twisting in these cables boosts immunity to EMI and electrical noise.
Detailed explanation-3: -CAT1 is typically used for telephone wire. This type of wire is not capable of supporting computer network traffic and is not twisted. CAT1is also used by telco companies providing ISDN and PSTN services. In such cases the wiring between the customer’s site and the telco’s network is performed using CAT 1 type cable.
