What is the LD50 value range for Dermal toxicity in the "Warning" hazard class?

Trace to 50-500
Trace to 200-2000
Trace to 500-5000
Trace to greater than 5000

The correct answer is: Trace to 200-2000

The LD50 value range for Dermal toxicity in the "Warning" hazard class is from trace to 200-2000. This means that the LD50 value for dermal toxicity could be as low as trace amounts, but never lower, and as high as 200-2000, but never higher. Options A, C, and D are incorrect because they either do not include the correct range of values or suggest values that are too high. For example, option C suggests that the LD50 could be as high as 500-5000, which is outside of the range given in the question. Option D suggests that the LD50 value could be greater than 5000, which is also outside of the given range. Option A suggests a range of 50-500, which does not include the upper limit of 200-2000. Therefore, option B is the only correct choice that accurately reflects the given range.
