Most soluble in water is:

(D) Sugar

Sugar is the most soluble chemical in water among the substances listed.
Sugar has six hydroxyl groups. They usually dissolve readily in warm or hot water.
Sugar is made from sucrose, and its molecule is more complex and bigger than the ions in the salt.
When energy is applied to polar sucrose molecules, intermolecular interactions with polar water molecules develop.
And because the intermolecular interactions are relatively weak, it provides enough energy to destabilize the structure of both the pure solvent and the solute.
As a result, sugar is most soluble in water.

Wrong ans plz correct it

this has to be common salt as NaCl is going to breakdown as ions easily as compared to sugar dissolving.

That's wrong cause I know that salt melts quicker than sugar an sugar only melt when water is hot
