A rod AB of uniform cross section consists of four sections AC, CD, DE and EB of different metals with thermal conductivities K, (0.8)K, (1.2)K and (1.50)K, respectively. Their lengths are, respectively, L, (1.2)L, (1.5)L and (0.6)L. They are joined rigidly in succession at C, D and E to form the rod AB. The end A is maintained at 100°C and the end B is maintained at 0°C. The steady state temperature of the joints C, D and E are, respectively, T_C, T_D and T_E. Column I lists the temperature differences (T_A - T_C), (T_C - T_D), (T_D - T_E) and (T_E - T_B) in the four sections and column II their values jumbled up. Match each item in column I with its correct value in column II.

A copper rod (initially at room temperature \(20^{\circ}C\)) of non-uniform cross section is placed between a steam chamber at \(100^{\circ}C\) and ice water chamber at \(0^{\circ}C\). \(A\) and \(B\) are cross sections as shown in figure. Then match the statements in column I with results in column II comparing only between cross section \(A\) and \(B\). (The mathematical expressions in column I have their usual meanings in heat transfer)
