Which of the following best describes the use of ENT in residential wiring?

The choice highlighting that ENT (Electrical Nonmetallic Tubing) can be used in exposed and non-exposed applications is accurate because it reflects the versatility and compliance with the National Electrical Code (NEC) regulations. ENT is designed to protect electrical conductors and cables in various environments, whether they are visible on the surface or hidden within walls and ceilings.

In exposed applications, ENT can shield wires from physical damage while also providing a lightweight and easily installed option for wiring. In non-exposed applications, it serves as a reliable conduit that maintains wire protection while helping to meet safety standards. This adaptability makes it suitable for a range of residential wiring scenarios, ensuring that installations remain both practical and code-compliant regardless of their visibility.

Other options are not aligned with the intended use and characteristics of ENT. For instance, ENT is quite effective in various voltage applications, not limited to low-voltage uses, and it is widely recognized for versatility in both residential and commercial environments, contrary to the notion that it is primarily for commercial use or not preferred for new installs.
