LD50 stands for which of the following?

Explanation:
LD50 represents the amount of a substance that would be expected to cause death in 50% of a defined experimental population. The “Lethal” part signals death, the “Dose” is the amount given, and the “50” indicates the median—half of the subjects would die at that dose. This metric is used in toxicology to compare acute toxicity across substances and is typically determined by dosing groups of animals (or cells in some in vitro setups) and observing mortality within a set time frame. Keep in mind that LD50 values depend on species, strain, age, sex, route of exposure, and experimental conditions, so they’re not universal. The other terms listed aren’t standard toxicity measures.
