ANFO stands for Ammonium Nitrate and Fuel Oil. This phrasing is significant in understanding how the explosive is composed and why it is widely used in various industries, particularly in construction and mining for blasting purposes.

Ammonium nitrate acts as the oxidizer in the explosive, while fuel oil serves as the fuel component, allowing for a significant energy release when detonated. The combination results in a cost-effective and efficient explosive that is relatively stable under normal handling conditions, making it safe for transport and storage.

The other options include incorrect terminology or components that do not accurately reflect the chemical makeup of ANFO, which can lead to misunderstandings about how this explosive functions or how it should be handled. Understanding the correct definition helps reinforce safety practices and regulatory compliance in scenarios involving explosives.
