There is not enough information to say.
You have two rods of the same length and diameter, but they are formed from different materials. The rods are used to connect two regions at different temperatures so that energy transfers through the rods by heat. They can be connected in series as the top figure or in parallel as in the bottom figure. In which case is the rate of energy transfer by heat larger?
The rate is larger when the rods are in series.
The rate is larger when the rods are in parallel.
The rate is the same in both cases.
