The term SI stands for the "International System of Units." This system is a globally accepted standard for measuring physical quantities and has been adopted in scientific and technical fields for consistency and clarity. The SI provides a coherent framework that covers a range of measurements, including length (meter), mass (kilogram), time (second), electric current (ampere), temperature (kelvin), amount of substance (mole), and luminous intensity (candela).

Using the SI system ensures that scientific communication is clear and reduces the potential for errors that can arise from using different systems or units. This standardization is especially important in international collaborations across various scientific disciplines.

The other options do not accurately reflect the meaning of the term SI. For instance, "International science of units" and "Internal science of universe" lack specificity and correct terminology, while "Internal systems" does not relate to measurement systems at all.
