Best answer
Correct answer is (c) Avogadro

The best explanation: Avogadro’s law is an experimental gas law combining & relating the volume of a gas to the amount of substance of gas present i.e’ directly proportional. This law is valid only for ideal gases. And also only when the pressure and temperature of the given substance are constant.
