The equation Fe + CuSO₄ → Cu + FeSO₄ illustrates the single displacement reaction. Hence Option (D) is the correct answer.

What is Single replacement reaction ?

A single replacement reaction, sometimes called a single displacement reaction, is a reaction in which one element is substituted for another element in a compound.

The starting materials are always pure elements, such as a pure zinc metal, iron or hydrogen gas, plus an aqueous compound.

Therefore, the equation Fe + CuSO₄ → Cu + FeSO₄ illustrates the single displacement reaction. Hence Option (D) is the correct answer.
