Solution

The correct option is B Henry's Law
Henry's law states that :
“The solubility of a gas in a liquid at a given temperature is directly proportional to its partial pressure of the gas present above the solution”
According to the statement when the pressure above the solution is 1 atm, 0.003 moles are dissolved, when the pressure is doubled, the solubility is also doubled.
So,
$Solubility \propto Pressure$

Thus the above statement confirms the applicability of Henry's law.
