What is the correct order of steps used to prepare a pure sample of copper(II) sulfate crystals from copper(II) oxide and sulfuric acid?
- Adissolving $\rightarrow$ crystallisation $\rightarrow$ evaporation $\rightarrow$ filtration
- Bdissolving $\rightarrow$ evaporation $\rightarrow$ filtration $\rightarrow$ crystallisation
- Cdissolving $\rightarrow$ filtration $\rightarrow$ crystallisation $\rightarrow$ evaporation
- Ddissolving $\rightarrow$ filtration $\rightarrow$ evaporation $\rightarrow$ crystallisation
