I.U. stands for:

Explanation:
International Units measure the biological activity of certain nutrients, not their mass. This question hinges on understanding that some vitamins are labeled by how potent they are rather than by weight. For fat-soluble vitamins like A, D, E, and K, the same amount in micrograms or milligrams can have different effects depending on the form and source, so labeling in International Units allows us to compare their actual potency across products. The other terms aren’t standard measurement systems used for vitamins, so they don’t fit.
