Wood, coal and charcoal are non-renewable sources of energy whereas, sun is a renewable source of energy.

Understanding the Odd One Out
In the given options, we are tasked with identifying which item does not belong with the others. Let's analyze each option:
Options Breakdown
- Wood
- A natural material derived from trees.
- Commonly used for construction and as fuel.
- Coal
- A fossil fuel formed from decomposed plants over millions of years.
- Used primarily for energy production and heating.
- Charcoal
- A black, porous material made by burning wood in limited oxygen.
- Primarily used for grilling and as a fuel source.
- Sun
- A star at the center of our solar system.
- Provides light and energy essential for life on Earth.
Why "Sun" is the Odd One Out
- Different Category
- Wood, coal, and charcoal are all forms of fuel or materials derived from organic matter.
- The sun, however, is an astronomical body that does not fit into the category of materials or fuels.
- Function and Usage
- The first three options serve practical purposes in heating, cooking, or construction.
- The sun provides energy but is not a material that can be used in the same way.
Conclusion
In summary, the odd one out is option 'C' - the "Sun," because it differs fundamentally from the other three options, which are all tangible materials used for similar purposes.
