Cv and Cp denote the molar specific heat capacities of a gas at constant volume and constant pressure, respectively. Then

A CpCv is larger for a diatomic ideal gas than for a monoatomic ideal gas.
B Cp+Cv is larger for a diatomic ideal gas than for a monoatomic ideal gas.
C Cp/Cv is larger for a diatomic ideal gas than for a monoatomic ideal gas.
D Cp.Cv is larger for a diatomic ideal gas than for a monoatomic ideal gas.
