In an isochoric process if \[{{T}_{1}}={{27}^{o}}C\] and \[{{T}_{2}}={{127}^{o}}C,\] then \[{{P}_{1}}/{{P}_{2}}\] will be equal to                                                     [RPMT 2003]

A)            9 / 59                                       

B)            2 / 3

C)            3 / 4                                         

D)            At constant volume \[P\propto T\]Þ \[\frac{{{P}_{1}}}{{{P}_{2}}}=\frac{{{T}_{1}}}{{{T}_{2}}}\]Þ\[\frac{{{P}_{1}}}{{{P}_{2}}}=\frac{300}{400}=\frac{3}{4}\]
