Correct option is D)
In an ion exchange using hard water is not a disadvantage since it becomes soft by exchanging anions or cations. Na+, Ca2+ and Mg2+ ions (from water) are exchanged with H+ ions (from cation exchange resins). Cl−, SO42− and NO3− ions (from water) are exchanged with OH− ions (from anion exchange resins).
