The correct option is D common salt
Explanation for correct option:
(d) Common salt
When we add water to the mixture of sand, common salt and camphor, we observe common salt dissolves completely in water forming a homogenous mixture of water and salt.
Explanation for incorrect options:
(a) Camphor
Camphor is a polar compound having a ketone group which does not dissolve in water.
(b) Camphor and common salt
Only common salt will dissolve in water, camphor will not.
(c) Sand
Sand when dissolved in water gives us a suspension which is a heterogeneous mixture in which sand settles down to the bottom of the tank when left undisturbed for some time.
Hence, option (d) is the correct option.
