Compare conduit types for typical indoor and outdoor applications.

• A. Electrical Metallic Tubing (EMT) is rigid metal for durable indoor/outdoor use; Polyvinyl chloride (PVC) is nonmetallic and corrosion-resistant; Flexible conduit is used for bends and motion.
• B. Electrical Metallic Tubing is nonmetallic; Polyvinyl chloride is flexible; Flexible conduit is rigid metal.
• C. PVC conducts electricity.
• D. Flexible conduit is not suitable for any bend.

Answer: (A)

Understanding conduit selection starts with how each type handles environment and bending needs. Rigid metal conduits like EMT are a sturdy choice for straight runs and protected protection, making them well-suited for typical indoor and outdoor installations when you use proper fittings and weather-rated components. Nonmetallic PVC conduit is inherently resistant to corrosion and moisture, so it’s a common outdoor option (and even suitable for underground exposure) because it won’t rust or deteriorate in wet conditions. Flexible conduit exists for spots where a straight run isn’t practical—areas that require frequent movement or tight bends around machinery or irregular layouts.

So the best choice matches these real-world roles: EMT as a rigid, durable option for indoor/outdoor runs; PVC as a corrosion-resistant nonmetallic option for outdoor or damp locations; and flexible conduit for bends and motion where rigid conduit isn’t feasible. The other statements misstate material properties—EMT isn’t nonmetallic, PVC isn’t flexible, and flexible conduit is designed to accommodate bends.
