A rod AB of uniform cross-section consists of 4 sections AC, CD, DE and EB of different metal with thermal conductivities K, `0.8,1.2K` and `1.5` respectively. Their lengths are respectively `L,1.2L, 1.5L` and `0.6L`. They are jointed rigidly in Succession at C, D and E to from the rod AB The end A is mainained at `100^(@)C` and the end B is the maintained at `0^(@)C`. The steady state temperatures p the joints C, D and E are respectively `T_(C),T_(D)` and `T_(E)` Match the following two columns
