Out of the four resources listed, three are alike in some manner and one is different. Select the odd one.

Correct option is B

The odd one out is selected based on the classification of resources. Let us analyze each option:

• Natural Gas: A fossil fuel derived from decomposed organic matter over millions of years.
• Biogas: A renewable energy source produced from organic waste like animal manure or plant material through anaerobic digestion.
• Coal: A fossil fuel derived from decomposed plant matter over geological timescales.
• Petroleum: A fossil fuel derived from ancient organic materials, predominantly plankton and algae.

Odd one out logic:

• Natural Gas, Coal, and Petroleum are non-renewable fossil fuels, formed over millions of years and limited in availability.
• Biogas, on the other hand, is renewable, produced relatively quickly, and can be continuously replenished using organic waste.

Thus, Biogas is the odd one out.
