Specific heats of an ideal gas at constant pressure and volume are denoted by $$\mathrm{C}_{\mathrm{p}}$$ and $$\mathrm{C}_{\mathrm{v}}$$ respectively. If $$\gamma=\frac{\mathrm{C}_{\mathrm{p}}}{\mathrm{C}_{\mathrm{v}}}$$ and $$\mathrm{R}$$ it's the universal gas constant then $$\mathrm{C}_{\mathrm{v}}$$ is equal to

A
$$\frac{(\gamma-1)}{(\gamma+1)}$$
B
$$\frac{(\gamma-1)}{\mathrm{R}}$$
C
$$\mathrm{R} \gamma$$
D
$$\frac{R}{(\gamma-1)}$$
