Homemade explosives are typically composed of which substances?

• A. Gases and Liquids
• B. Metals and Salts
• C. Fuels and Oxidizers
• D. Chemicals and Flames

Answer: (C)

Explosives work because a fuel and an oxidizer react together in a highly accelerated way. The oxidizer provides the oxygen needed for the reaction, while the fuel supplies the chemical energy that drives it. When these two are combined in the right proportions and kept under confinement, the energy is released so quickly that a shock wave is produced. That’s why fuels and oxidizers are the correct general description of what makes up many explosive compositions. The other options don’t capture this essential pairing: simply gases and liquids don’t explain the mechanism; metals and salts describe materials rather than the reactive duo; and chemicals and flames describe outcomes or components of a reaction, not the fundamental mix that enables an explosive effect.
