Swollen feets and ankle can be naturally cured by dipping them in salt water. Suggest the mechanism involved in this treatment.
(A) Diffusion
(B) Osmosis
(C) Plasmolysis
(D) Deplasmolysis

Dear student

Option C is correct.
Plasmolysis is the process involved.
In this , outside solution in which feets are dipped is a salt water which is more concentrated, it has more salt and less water. on other hand swollen feet has more water. So water moves from its higher concentration to lower concentration. So feet cell will shrink leading to plasmolysed cell .
