Which of the following is the correct abbreviation for milliliter?

The correct abbreviation for milliliter is "ml." This abbreviation is widely accepted in both medical and scientific communities, ensuring clear communication regarding liquid volume measurements. A milliliter is a metric unit of volume that is equal to one-thousandth of a liter, particularly useful in dosage calculations and measurements in healthcare settings.

The abbreviation "ml" is concise and easily distinguishable, which is vital in avoiding confusion with other measurements. Using the full word "milliliter" is also appropriate, but the abbreviation "ml" is preferred for efficiency in documentation and prescription writing.

The other options refer to different units of measurement, which are not related to milliliters. "Oz" stands for ounces, "qt" refers to quarts, and "tbsp" signifies tablespoons. All these measure volume, but they are part of different systems (imperial or customary) and do not align with the metric system that milliliters belong to.
