Solution
The correct option is D thermite reaction, exothermic
Thermite is a pyrotechnic composition of metal powder, fuel and metal oxide. When ignited by heat, thermite undergoes an exothermic reduction-oxidation reaction. Fuels include Al, Mg, Ti, Zn, Si, B and Al is common because of its high boiling point and low cost. Oxidizers include boron (III) oxide, iron (III) oxide, copper (II) oxide.
