A container is divided into two equal part I and II by a partition with a small **** of diameter d. The two partitions are filled with same ideal gas, but held at temperature TI = 150 K and TII = 300 K by connecting to heat reservoirs. Let λI and λII be the mean free paths of the gas particles in the two parts such that d >> λI and d >> λII. Then λI/λII is close to -
(A) 0.25
(B) 0.5
(C) 0.7
(D) 1.0
