Correct Answer:
A. It is produced from renewable sources like vegetable oils.
Explanation:
Biodiesel is regarded as a sustainable substitute for conventional diesel primarily because it is manufactured from renewable biological resources, such as vegetable oils, animal fats, or recycled grease. Unlike traditional petroleum diesel, which is derived from finite crude oil reserves, biodiesel relies on feedstocks that can be replenished through agriculture and natural cycles. This closed-carbon cycle helps reduce the overall environmental footprint, as the plants used for production absorb carbon dioxide while growing, partially offsetting the emissions released during combustion.
