Answer to the Question

The process of converting oils into biodiesel is called a. transesterification.

Explanation

Transesterification is a chemical reaction that involves the transformation of fatty acids in oils (triglycerides) into biodiesel and glycerol, using alcohol (usually methanol or ethanol) and a catalyst (often sodium or potassium hydroxide). This process allows for the production of biodiesel from various sources, including vegetable oils and animal fats. The other options listed do not pertain to the production of biodiesel:

• b. Pyrolysis refers to the thermal decomposition of organic materials at elevated temperatures in the absence of oxygen.
• c. Fermentation is a biological process that converts sugars into acids, gases, or alcohol.
• d. Combustion is a chemical reaction that involves the burning of fuel in an oxidizing environment.

Thus, the correct answer is a. transesterification.
