Using Gay-Lussac's Law which states that the pressure of a fixed amount of gas at constant volume is directly proportional to its absolute temperature, we can use the formula P1/T1 = P2/T2, where P1 and T1 are the initial pressure and temperature respectively, and P2 is the final pressure we want to find.

Rearranging the formula, we get T2 = (P2*T1)/P1

Substituting the values given, we get T2 = (8.00*293)/4.00 = 586 K = 313°C

Therefore, the temperature at which the pressure is 8.00 atm is 313°C, which is option D.
