An ideal gas (whose \( \frac{c_{p}}{C_{v}}=\lambda \), and internal energy \( U \) at
\( \mathrm{P} \) absolute zero temp. is equal to zero) undergoes a reversible

W adiabatic compression. If \( U, p, V, T \) represent the internal energy, pressure, volume and temperature respectively of the ideal gas, then
(A) \( U V^{\lambda}= \) const
(B) \( U p^{\lambda}= \) const
(C) \( V U^{\frac{1}{\lambda-1}}= \) const
(D) \( T V^{\lambda-1}=\mathrm{const} \)
