2. NEC Section 314.6 A

3. NEC Section 250.114

4. NEC Section 314.6 B

The correct answer is: NEC Section 250-119

The correct reference for the identification of equipment grounding conductors is NEC Section 250.119. This section specifically outlines the requirements for the proper identification of equipment grounding conductors, which is crucial for ensuring safety and compliance in electrical installations. Proper identification includes the use of certain colors and markings to indicate that a conductor is an equipment grounding conductor, helping to prevent confusion with other conductors and enhancing safety during installation and maintenance. While the other sections mentioned may cover different aspects of the National Electrical Code, they do not specifically address the identification of equipment grounding conductors. Section 250.114 deals with equipment grounding conductors and their required applications; however, it does not focus on the identification. Sections 314.6 A and 314.6 B pertain to the mounting and support of boxes and conductors in various configurations, which are unrelated to the specific identification of grounding conductors.
