• A. 0
• B. 1
• C. 2
• D. 3

Answer: (B)

Pathway survivability is about keeping critical electrical pathways up and running during a fire, by using protection that limits fire damage to the cables and their routes. The level described here matches Level 1 because it calls for pathways that are fully protected by an automatic sprinkler system and for interconnecting conductors to be run in metal raceways. Sprinkler protection helps slow or limit fire exposure to the pathways, while metal raceways provide physical and fire-resistance protection for the conductors inside. Together, these measures establish a basic, minimum level of survivability for essential electrical pathways. Higher levels would require additional safeguards beyond these protections, while lower levels would involve less protection. So this description aligns with the level 1 standard.
