• C. Article 310
• D. Article 400

Answer: (C)

Article 310 of the National Electrical Code (NEC) specifically addresses the requirements for conductors and cables. This article provides essential guidelines on various aspects, including conductor ampacity, insulation types, and installation methods. It details how to properly size and select conductors based on their intended use, environmental factors, and installation conditions, ensuring that electrical systems are safe and efficient. In contrast, other articles like Article 300 focus on general wiring methods and installation practices, Article 250 deals with grounding and bonding requirements, and Article 400 pertains to flexible cords and cables. While all these articles play important roles in the overall wiring landscape, Article 310 is dedicated specifically to the needs and criteria for conduits and cables, making it the relevant choice for this question.
