Correct Answer: Option C

Explanation

The blue color of the copper sulfate solution fades and eventually turns a pale green or greenish blue color. This is because the iron displaces the copper from the copper sulfate solution, forming ferrous sulfate (FeSO4). A visible change is observed when a strip of iron is placed in an aqueous solution of copper sulfate (CuSO4)
