Correct:
C
Explanation
Fire classification in India is primarily based on the Bureau of Indian Standards (IS 15683:2018), which categorizes fires based on the fuel source:
- Class A: Fires involving ordinary solid combustibles like wood, paper, and textiles.
- Class B: Fires involving flammable liquids or liquefiable solids such as oils, grease, and paints.
- Class C: Fires involving flammable gas substances like LPG, CNG, and methane.
- Class D: Fires involving combustible metals such as Magnesium, Aluminium, and Sodium.
- Class F: Fires involving cooking media (fats and oils).
It is important to note that while the US (NFPA) standard classifies electrical fires as Class C, the Indian Standard (IS) and European standards designate Class C for gases. Electrical fires are generally treated as a hazard category requiring non-conductive extinguishing agents rather than a separate material class.
