Which statement about lithium-based batteries is true?

• A. Lithium is highly flammable
• B. Lithium reacts with water
• C. Lithium batteries do not pose any fire risk
• D. Lithium batteries are considered a hazardous material and a fire hazard

Answer: (C)

Lithium-based batteries carry real fire and hazard risks, which is why they are treated as hazardous materials in transport and handling. If a lithium battery is damaged, shorted, overcharged, or exposed to high heat, it can undergo thermal runaway and ignite. This danger exists for both lithium-ion cells and lithium-metal types, though the specifics differ (lithium metal reacts strongly with water and air, while lithium-ion cells can combust if their internal safety mechanisms fail). That’s why the statement emphasizing them as hazardous material and a fire hazard is the accurate one. Saying they pose no fire risk is incorrect, and while lithium metal’s reaction with water is real, it doesn’t fully describe the broader safety context of lithium-based batteries used in drones. The notion that they are simply “highly flammable” is incomplete because the hazard relates to potential fires from thermal runaway in the battery, not just a general flammability of the metal itself.
