For the following Assertion and Reason, the correct option is

Assertion (A) : When $Cu$ (II) and sulphide ions are mixed, they react together extremely quickly to give a solid.

Reason (R) : The equilibrium constant of ${Cu}^{2 +} (aq) + S^{2 -} (aq) ⇌ CuS (s)$ is high because the solubility product is low.

A sample of water was checked for the suitability for drinking and was subjected to a chemical test. Pure zinc granules and sulphuric acid were added to the water sample. The effervescence that resulted from the reaction was bubbled through a tube containing lead acetate solution. A black precipitate appeared. The outgoing gas was subsequently passed through a heated copper tube, and a black mirror appeared on the wall of the tube. The first and the second black substances, respectively, are:
