B) 38°C
C) 311°C
D) 273°C
E) 122°C

According to Gay-Lussac's law, for a gas at constant volume, the pressure is directly proportional to its temperature in Kelvin. If the pressure doubles, the temperature in Kelvin must also double. The initial temperature is 19°C, which is 292K. Doubling this gives 584K, which is 311°C.
