What type of material consists of a fuel and oxidizer used to set off explosives?

The correct answer, which refers to a material consisting of a fuel and oxidizer used to set off explosives, is "Blasting Agent." A blasting agent is specifically designed to be initiated by a detonator and contains both a fuel component and an oxidizing agent that contribute to the explosive reaction. These agents are generally not sensitive to heat or shock and require a specific means of initiation, which distinguishes them from more sensitive explosives.

In the context of explosives, the composition of a blasting agent is crucial because it determines how the explosive will behave under various conditions. Blasting agents are typically used in mining, construction, and demolition applications where controlled explosive energy is needed.

Other choices, such as "Incendiary Device" and "Combustion Agent," describe materials used for different purposes. An incendiary device is designed to start fires through combustion without the explosive characteristics of a blasting agent. A combustion agent refers to any substance that can assist in the burning process but does not specifically pertain to explosive materials like blasting agents do. Meanwhile, "Explosive Mixture" is a more general term that can refer to a combination of materials that can explode but doesn’t specify the nuanced characteristics essential in the context of blasting agents.
