A. {'text': 'Proportional to its mole fraction', 'label': 'A'}

1. Henry law addresses the solubility of a gas in a liquid at a given temperature.
2. It states p = K_H × x, where p is partial pressure of the gas above the solution.
3. So the partial pressure is directly proportional to the mole fraction of dissolved gas.
4. K_H, Henry constant, depends on gas and temperature (increases with temperature for most gases).
