Calcium sulphate (CaSO4) being less soluble in water causes permanent hardness in water.

Which one of the following process will produce hard water?
Saturation of water with $C a S O_{4}$
Addition of $N a_{2} S O_{4}$ to water
Saturation of water with $M g C O_{3}$
Saturation of water with $C a C O_{3}$

Calcium sulphate $(C a S O_{4})$ being less soluble in water causes permanent hardness in water.
