A rod of length `L` and uniform cross-sectional area has varying thermal conductivity which changes linearly from `2K` at end `A` to `K` at the other end `B`. The ends `A` and `B` of the rod are maintained at constant temperture `100^(@)C` and `0^(@)C`, respectively. At steady state, the graph of temperture : `T=T(x)` where `x=` distance from end `A` will be
