DENSITY(d)= pM/RT,  i.e, it is directly proportional yo pressure and inversely proportional to temperatutre. Thus the condition is highest pressure and low temperature

PV =nRT            ( n is number of moles of gas)

n = mass of gas /M.wt   & dencity(d) is mass/V

PV=(mass) RT/M.wt

P=dRT/M.wt         or

d= p(M.wt)/RT

from above eq , if the pressure is more and temprature is less then dencity will be high.....

therefore for option b dencity is maximum......
