Vedclass · Answer

(C) Polymetaphosphates,such as sodium hexametaphosphate $(Na_6P_6O_{18})$,are commonly used as water softeners.

These polyphosphates form stable,soluble complexes with these cations,thereby preventing them from reacting with soap to form scum. Therefore,the correct mechanism is the formation of soluble complexes with the cations of hard water.
