I'll solve this problem step by step, following the specified formatting guidelines:

Step 2:
: Understand SI Base Units

The International System of Units (SI) defines seven base units for fundamental physical quantities. These base units are the fundamental building blocks for measuring different aspects of the physical world.

Step 3:
: Identify the Base Unit for Temperature

Fahrenheit: $$\text{Another temperature scale, not a base unit}
Among the given options, we need to determine which represents the SI base unit for temperature. Let's analyze each option: A. B. C. D.

Step 4:
: Confirm Kelvin as the Base Unit

It is named after Lord Kelvin and is defined by absolute zero, which is $$0 \text{ K}$$ (zero kelvins).
The Kelvin scale is the standard SI base unit for thermodynamic temperature.

Final Answer

Kelvin is the SI base unit of temperature. Key Points: - SI base units are fundamental and cannot be derived from other units - Kelvin is defined with its zero point at absolute zero - Other temperature scales (Celsius, Fahrenheit) are not base units
