Article 384 discusses which type of raceway?

Article 384 of the National Electrical Code (NEC) specifically addresses Strut-Type Channel Raceway, which is designed to support electrical conductors and other equipment. This type of raceway is often used in applications where there is a need for secure mounting and organization of cables in commercial and industrial settings.

Strut-type channel raceways are typically constructed of metal and feature a channel shape that allows for the easy insertion of raceway fittings and other accessories. They provide a flexible and efficient means of protecting conductors while allowing for easy access to the cables for maintenance and modifications.

The other options, while they are different types of raceways discussed in various parts of the NEC, do not fall under Article 384. Surface metal raceways, cablebus, and cellular concrete floor raceways are covered in different sections of the code, each addressing specific requirements and applications suited for those types of raceways.
