Gas law was given by
 A Boyle B Ostwald C Faraday D Arrhenius
Explanation:

Detailed explanation-1: -Boyle’s law-named for Robert Boyle-states that, at constant temperature, the pressure P of a gas varies inversely with its volume V, or PV = k, where k is a constant.

Detailed explanation-2: -Gay-Lussac discovered one of the fundamental laws of gases, the law of combining volumes. French chemist Joseph Louis Gay-Lussac proposed two fundamental laws of gases in the early 19th century. While one is generally attributed to a fellow countryman, the other is well known as Gay-Lussac’s law.

Detailed explanation-3: -Boyle’s law is a gas law that states that a gas’s pressure and volume are inversely proportional. When the temperature is kept constant, as volume increases, pressure falls and vice versa.

Detailed explanation-4: -Boyle’s Law tells us that the volume of gas increases as the pressure decreases. Charles’ Law tells us that the volume of gas increases as the temperature increases. And Avogadro’s Law tell us that the volume of gas increases as the amount of gas increases.

Detailed explanation-5: -Boyle’s law In 1662 Robert Boyle studied the relationship between volume and pressure of a gas of fixed amount at constant temperature. He observed that volume of a given mass of a gas is inversely proportional to its pressure at a constant temperature.
