Step 1: Thermite is a pyrotechnic composition of metal powder and metal oxide. Step 2: The most common and classic thermite mixture consists of Aluminium (Al) powder as the fuel and Iron(III) oxide (Fe2O3) as the oxidizer in a 1:3 stoichiometric ratio. Step 3: Consequently, thermite is a mixture of Al powder and Fe2O3, matching option (b).
