You need to remember what a solute, a solvent and a solution represent. A solvent in a solution represents the substance that performs the dissolving process, while the solute represents the substance that is dissolved by the solvent. A solution represents the mixture of two substances.
You need to select the statement found at the point D, since it is incorrect. The statement claims that "gases are not able to act as a solvent in the solute", which is not true and it can be contradicted by the following example. It is known that atmosphere consists of oxygen, carbon dioxide, nitrogen, water vapours and neon. Since in a solution, the substance that is present in the largest amount is considered as being the solvent, then it can be concluded that nitrogen represents the solvent in atmospheric air, since the atmosphere contains 78.09% nitrogen, the rest of gases being found in smaller amounts.
The final conclusion, based on the example presented above, is that the gases are able to act as solvent in a solution.
