Which term denotes the International System of Units used as the standard measurement system in science?

• A. SI System
• B. Law
• C. Independent Variable
• D. Theory

Answer: (A)

The main idea here is recognizing the standardized measurement framework scientists use worldwide. The International System of Units, abbreviated SI, is the system that defines units like meter, kilogram, and second, and it provides a consistent way to measure and compare physical quantities across experiments and publications. The term in the question, “SI System,” directly refers to that framework. In contrast, a law explains natural relationships, an independent variable is what a researcher changes in an experiment, and a theory is a well-supported explanation. Those ideas are important, but they aren’t about a standard system of measurement.
