The molar specific heats of an ideal gas at constant pressure and volume are denoted by  \[{{C}_{p}}\] and \[{{C}_{V}}\] respectively. If \[\gamma =\frac{{{C}_{p}}}{{{C}_{V}}}\] and R is the universal gas constant, then \[{{C}_{V}}\] is equal to                                                                                                                                 [NEET 2013]

A)  \[\frac{1+\gamma }{1-\gamma }\]         

B)       \[\frac{R}{(\gamma -1)}\]

C)  \[\frac{(\gamma -1)}{R}\]          

D)       \[\gamma R\]
