Solution

The correct option is B False
Hard water is not suitable for washing clothes.
Calcium (Ca⁺²) and Magnesium (Mg⁺²) ions from the hard water react with the anions of the fatty acids present in the soap to form curdy white precipitates.
As a result, hard water is unable to produce lather with soap.
Hence, soft water should be used to wash the clothes.
