Which option is the abbreviation for International Units?

Explanation:
Recognizing the standard abbreviations used for dosage units is the idea here. International Units are abbreviated as IU, a shorthand that conveys potency or activity rather than a concrete weight. That makes IU the correct choice because it is the conventional abbreviation for International Units used in pharmacology and veterinary meds. The other options don’t fit as unit abbreviations: writing out “International units” is just the full words, not an abbreviation; q.s. stands for quantum sufficit (as much as is needed); PRN stands for pro re nata (as needed).
