The van der Waals constants for a gas are: \( a=4 \mathrm{~L}^{2} \mathrm{~atm} \) \( \mathrm{mol}^{-2}, b=0.04 \mathrm{~L} \mathrm{~mol}^{-1} \). Its Boyle temperature is roughly
(A) \( 100^{\circ} \mathrm{C} \)
(B) \( 1220 \mathrm{~K} \)
(C) \( 1220^{\circ} \mathrm{C} \)
(D) \( 1600 \mathrm{~K} \)
