A monoatomic ideal gas is taken through a reversible process whose equation is given by: \[p=k{{V}^{-\frac{1}{2}}}\] Where p is the pressure and V is the volume of the gas. The molar heat capacity of the gas in the above process, is

• A. \[{{C}_{p}}+lR\]         
• B.        \[{{C}_{v}}-lR\]  
• C. \[{{C}_{v}}+lR~\]       
• D.        \[~{{C}_{p}}+2R\]
