petroleum, because it comes in many forms such as oil shales, tar sands, etc.
natural gas, because it is the most efficient and produces the fewest emissions
oil, because many byproducts can be made so it is very efficient and productive
coal, because new technology has improved its efficiency

Explanation:

Step1: Analyze each option

• Petroleum: Comes in many forms but still has significant emissions.
• Natural gas: Is more efficient and emits fewer pollutants like carbon dioxide, sulfur dioxide, etc. compared to other fossil fuels.
• Oil: Byproducts are useful but it still has high emissions.
• Coal: Even with new technology, it is a major emitter of pollutants.

Answer:

natural gas, because it is the most efficient and produces the fewest emissions.
