    According to kinetic theory of gas for given mass M of gas occupying volume V the pressure P is given P = ( 1M)/( 3V) C^(2) where C is r.m.s. velocity of gas. Then Column-I gives the conditions while Column-II gives dependence of pressure of gas. Match the correct options in two columm. {:("Column-I","Column-II"),("A) If volume and temperature of gas are constant. then pressure exerted by gas is","P) Proportional to mass"),("B) If mass and temperature of gas are constant, then pressure exerted by gas is","Q) Constant"),("C) If mass and volume of gas are constant, then","R) Inversely proportional to volume pressure exerted by gas is"),("D) For give~ mass of gas at constant temperature in metal container, then the pressure exerted by gas is","S) Proportional to absolute temperature of gas"):}
