Which term refers to additives that enhance explosives?

• A. Precursors
• B. Catalysts
• C. Stabilizers
• D. Initiators

Answer: (A)

Think about how terms are used around energetic materials. Precursors are the starting chemicals used to make explosives; they provide the building blocks that enable the explosive compound to be formed. In that sense, they act as additives that enable the explosive’s existence and development, which is why they’re the best fit among the options. A catalyst speeds a reaction but isn’t typically an ingredient added to an explosive to boost performance; stabilizers are about improving shelf life and safety; initiators are components that trigger the reaction. So the term that best matches “additives that enhance explosives” in this context is precursors.
