A) it is converted to an SI unit of measurement

Explanation:

The SI, System International units are the fundamental units used to measure the scientific quantities.

Example of SI units are Kilogram (km) for distance, liter (l) for liquid, centimeter (cm), and meter (m) for size of the object or short distance etcetera.

SI units help to differentiate quantities from each other and without using SI unit, no one can identify the category of the quantity whether it is distance, size or volume.

Hence, the correct answer is "A) it is converted to an SI unit of measurement".
