ANSWER: d) International System of Units (SI)
EXPLANATION:
The most widely used and accepted unit system worldwide is the Metric system, also known as the International System of Units (SI). It is used in the majority of countries across the globe, including scientific, industrial, and everyday applications. The Metric system provides a coherent and decimal-based system of measurement, which simplifies conversions between different units and promotes international standardization. While the United States and a few other countries still use the United States customary units, which are derived from the older British Imperial system, the Metric system is the preferred and dominant system globally.
