All the rods have same conductance `'K'` and same area of cross section '`A'`. If ends A and C are maintained at temperature `2T_(0)` and `T_(0)` respectively then which of the following is`//`are correct?

Four identical rods AB, CD, CF and DE are joined as shown in figure. The length, cross-sectional area and thermal conductivity of each rod are l, A and K respectively. The ends A, E and F are maintained at temperature T_(1) , T_(2) and T_(3) respectively. Assuming no loss of heat to the atmosphere, find the temperature at B.
