(B) The Alumino-thermite process involves the reduction of metal oxides (like $Cr_2O_3$ or $MnO_2$) using aluminum powder as a reducing agent.The reaction is highly exothermic: $Cr_2O_3 + 2Al ightarrow 2Cr + Al_2O_3 + 	ext{Heat}$.In this reaction,aluminum gets oxidized to $Al_2O_3$ and reduces the metal oxide to its corresponding metal.Therefore,aluminum acts as a reducing agent.

In the process of extracting chromium and manganese metals from their oxides (Alumino-thermite process),aluminum is used as a ...... .
