The correct answer is B. sulphur dioxide.

When copper powder reacts with concentrated sulfuric acid, the gas produced is sulfur dioxide (SO2). This reaction is represented by the equation:

Cu(s) + 2H2SO4(aq) -> CuSO4(aq) + SO2(g) + 2H2O(l)

Sulfur dioxide is a colorless gas with a pungent odor and is commonly produced in various chemical reactions involving sulfur-containing compounds.
