    The answer is; D

    Solvation is the process by which the molecules of a solute interact with those of a solvent to form solvates. The interaction involves the formation of temporary bonds between the molecules of the elements. These bonds in this rection absorb energy from the atmosphere hence the reaction feels cold to the touch. This is called an endothermic reaction.
