# By which of the following reactions is copper obtained?

$(a)\;Cu_2S+Feo \longrightarrow 2Cu+FeS_2 \\(b)\;Cu_2S+Fe \longrightarrow Fe^2+Cu \\(c)\;Cu_2S+Feo \longrightarrow 2Cu+FeO \\ (d)\;Cu_2S+2Cu_2O \longrightarrow 6Cu+So_2$

$Cu_2S+2Cu_2O \longrightarrow 6Cu+So_2$ is correct
Hence d is the correct answer.
