The SI unit of temperature is

Options

A. kelvin
B. second
C. mole
D. candela

Answer

To solve the question regarding the SI unit of temperature, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the SI unit of temperature. SI stands for the International System of Units, which is the standard system used in science and engineering.

2. **Identify the Options**: The question may provide multiple options. In this case, we need to evaluate them to find the correct one. The options might include units like Kelvin, Celsius, Fahrenheit, etc.

3. **Recall the SI Unit of Temperature**: The standard SI unit for measuring temperature is Kelvin (K). This is a fundamental unit in the SI system.

4. **Evaluate Other Options**: If there are other options provided:
- Celsius (°C) is a commonly used unit for temperature but is not the SI unit.
- Fahrenheit (°F) is another temperature scale but is also not the SI unit.
- Other units like mole (for amount of substance) and candela (for luminous intensity) are also not relevant to temperature.

5. **Conclusion**: After evaluating the options, we conclude that the SI unit of temperature is Kelvin (K).

### Final Answer:
The SI unit of temperature is Kelvin (K).
