_____ is an enclosed or semi-enclosed channel that protects, routes, and hides cables and wires.

• A. Raceway
• B. Conduit
• C. Duct
• D. Cable tray

Answer: (A)

The concept being tested is a protective path for cables. A raceway is an enclosed or semi-enclosed channel designed to protect, route, and conceal electrical conductors, keeping cables organized and shielded from damage as they run through walls, floors, or along surfaces. Conduit is a type of raceway—specifically a rigid or flexible tube used to enclose conductors—so it fits under the broader term, but the description points to the general idea of a raceway. Ducts are typically used for larger pathways and can involve air or other systems, not primarily for concealing standard electrical cables. Cable trays are open and provide support rather than enclosing the cables, so they don’t match the description. Hence, the best term is raceway.
