Five rods of the same dimensions are arranged as shown. They have thermal conductivities k1, k2, k3, k4 and k5. When points A andB are maintained at different temperatures, no heat flows through the central rod. It follows that :(a) k1 = k4 and k2 = k3(b) k1/k4 = k2/k3(c) k1k4 = k2k3(d) k1k2 = k3k4pls rewply fast
