Under what circumstances does hydrometallurgy prove effective in extracting copper, while zinc extraction is not feasible?

Options

1. AZinc forms stable complexes with water, hindering hydrometallurgical processes.
2. BZinc has low solubility in water, making it unsuitable for hydrometallurgical extraction.
3. CCopper exhibits a higher affinity for water, enabling effective hydrometallurgical extraction.
4. DZinc reacts chemically with water, impeding the hydrometallurgical process.
