• D. SI units are less accurate than traditional measurement systems.

Answer: (C)

Verified step by step guidance

1. Understand that SI units (International System of Units) are a globally accepted system of measurement used in science to ensure consistency and clarity.
2. Recognize that SI units are not arbitrary; they are based on fixed constants and definitions that do not change frequently, which helps maintain accuracy and reliability.
3. Note that SI units are used across many scientific disciplines, not just chemistry, making them a universal language for scientists.
4. Identify that the main benefit of SI units is their standardization, which allows scientists worldwide to communicate and compare results without confusion.
5. Conclude that the correct benefit is that SI units provide a standardized system that allows scientists worldwide to communicate results clearly.
