Solution

The correct option is D boiling
By boiling, the bicarbonates undergo decomposition to form insoluble carbonates of $C a / M g$ which can further be removed by filtration.
$C a {({H C O}_{3})}_{2} (a q) \to C a C O_{3 (s)} + {C O}_{2 (g)} + H_{2} O (l)$
$M g {(H C O)}_{3} (a q) \to M g {C O}_{3 (s)} + {C O}_{2 (g)} + H_{2} O_{(l)}$
Then the water obtained will be free from $C a$ and $M g$ ions and is soft.
