Which term represents the International System of Units, the standard unit system in measurements?

• A. Law
• B. Theory
• C. Control
• D. SI System

Answer: (D)

Understanding what is meant by a standard measurement system is what this question tests. The term that represents the International System of Units is the SI System. SI is the globally adopted set of base units—meter, kilogram, second, and so on—along with prefixes and derived units that let scientists measure length, mass, time, temperature, electric current, amount of substance, and luminous intensity consistently. Using SI enables clear comparisons of measurements across experiments and countries. The other words—law, theory, and control—describe ideas about how nature behaves or how systems are managed, not a system of measurement. So the familiar standard name for the measurement system is the SI System.
