The solubility of a gaseous substance is dependent on the following factors:
III. Temperature: Generally, the solubility of gases in liquids decreases as temperature increases. This is because as temperature rises, the kinetic energy of the gas molecules increases, leading to more rapid movement and escape from the liquid phase.
IV. Pressure: Henry's law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid. So, an increase in pressure typically leads to an increase in solubility and vice versa.
So, the correct options are III and IV.

The solubility of a gas depends on the Nature of solvent II. Nature of solute III. Temperature IV. Pressure
so option D should be the answer.
