What is the LD50 range for Inhalation toxicity in the Hazard Class IV category?

Trace to 0.2
Trace to 2
Trace to 20
Greater than 20

The correct answer is: Greater than 20

The LD50 (Lethal Dose 50%) range for Inhalation toxicity in the Hazard Class IV category is greater than 20. This means that the amount or concentration of a substance needed to cause death in 50% of the test subjects is greater than 20 milligrams per cubic meter of air. While options A, B, and C all have the range starting at "Trace," signifying a small amount, they have different upper limits, making them incorrect. Option A has the range ending at 0.2, which is a much lower limit compared to option D. Option B has a limit of 2, which is also much lower than option D. Option C has a limit of 20, which is still lower than option D and falls within Hazard Class III.
