The correct answer is: $K_{\mathrm{H}}$ value increases on increasing the temperature of the solution.
Among the given statements only (c) statement is correct about the Henry's law constant. Other statement are incorrect because
(a) $K_{\mathrm{H}}$ is a function of the nature of the gas and solvent used, thus $K_{\mathrm{H}}$ value is not same for a gas in any solution.
(b) Higher the $K_{\mathrm{H}}$ value, less the solubility of the gas.
(d) Easily liquefiable gases usually have higher $K_{\mathrm{H}}$ values.
