Which statement about LD50 is true?

Explanation:
LD50 is the dose that kills 50% of exposed individuals, so it directly reflects acute toxicity. The smaller the dose needed to reach that 50% mortality, the more toxic the substance is. LD50s are not limited to inhalation; they can be determined for oral, dermal, or inhalation exposure, and you can compare values to rank toxicity only when the route and species are the same. So the true statement is that a lower LD50 value indicates higher acute toxicity.
