The correct option is A greater for gases with lower solubility.
Henry's law states that the amount of gas dissolved in a liquid is proportional to its partial pressure above the liquid. The proportionality constant is called Henry’s constant (KH).
P=KHX
where,
P= Partial pressure of gas
X= solubility of gas in liquid
KH = Henry’s constant
KH=PX
The higher the value of KH at a given pressure, the lower is the solubility of the gas in the liquid. The Henry’s constant KH is also a function of the nature of the gas.
Hence, option (B) is correct.
