Which type of cable is listed for use in Zone 1 or Class 1, Division 1 locations with regard to its protective sheath?

The correct choice is Type MC_HL cable, which is designed to be used in hazardous environments such as Zone 1 or Class 1, Division 1 locations. The "MC_HL" designation stands for "Metallic Sheathed, Hazardous Locations." This type of cable has specific features that allow it to withstand the rigors of environments where flammable gases or vapors may be present. The protective sheath of Type MC_HL cable provides not only mechanical protection but also some resistance to corrosive atmospheres, which is crucial in preventing potential ignition sources.

The design rules and standards governing MC_HL cable ensure that it meets the stringent requirements for use in areas classified as hazardous. This includes maintaining an appropriate level of shielding and insulation to mitigate the risk of sparks or heat that could ignite flammable substances. Moreover, the cable's construction allows for use in exposed outdoor locations, which is often necessary for industrial applications in hazardous areas.

In contrast, the other types of cables listed do not have the same level of certification or suitability for these specific hazardous locations. For example, Type TR cable is not explicitly designed for the same levels of protection in these zones, while Type NM cable is specifically made for non-hazardous general-purpose use and
