Solution
The correct option is DCaCl2 CaCl2 is an electrolyte. It dissociates in solution to form ions. Hence, it will dissolve in water to form an ionic solution.
On the other hand, O2, CH4 and C12H22O11 are non electrolytes. They do not dissociate into ions. Hence, they will dissolve in water to produce molecular solutions.
