One mole of an ideal monatomic gas is taken along the path ABCA as shown in the PV diagram. The maximum temperature attained by the gas along the path BC is given by:

A

$$\frac{25}{4} \frac{P_0 V_0}{R}$$

B

$$\frac{5}{8} \frac{P_0 V_0}{R}$$

C

$$\frac{25}{8} \frac{P_0 V_0}{R}$$

D

$$\frac{25}{16} \frac{P_0 V_0}{R}$$
