Hint: The behaviour of the ideal gases is mostly defined by the common equation \[PV = nRT\] , which is a combination of various laws. So, the behaviour of the gas is determined by all the given laws in one or the other way.

Complete answer:
So, to get the answer of the question, let’s understand each law in brief.
First Boyle’s law states that at the given temperature for the fixed amount of gas, the volume of the gas is inversely proportional to the pressure of the gas.
Coming to Charle’s law, it states that at the given pressure, the volume of the gas is directly proportional to the temperature of the gas.
Avagadro’s principle is a combination of two laws i.e. of Dalton’s atomic theory and the Gay Lussac’s law. So, Avagadro’s principle states that at constant pressure and temperature, the volume of the gas is directly proportional to the number of molecules present in the gas.
Now, looking at our Dalton’s law – it states that the total pressure of the mixture of the gas is equal to the sum of the partial pressure of each gas component.
Hence, on the basis of our above discussion, the correct option is (A) i.e. Boyle’s law.
Therefore, According to Boyle’s law Pressure is inversely proportional to volume.


Note:
According to ideal gas law, the ideal gas is supposed to be the gas having perfect elastic collisions and the gas with no intermolecular force of attraction between the gas particles or between the gas particles and the container.
