Temperature at midway between 2 rods

Two long, thin, solid cylinders are identical in size, but they are made of different substances with two different thermal conductivities. The two cylinders are connected in series between a reservoir at temperature \(T_{hot}\) and a reservoir at temperature \(T_{cold}\). The temperature at the boundary between the two cylinders is \(T_b\). One can conclude that :-

(A) \(T_b\) is closer to \(T_{hot}\) than it is to \(T_{cold}\)

(B) \(T_b\) is closer to \(T_{cold}\) than it is to \(T_{hot}\)

(C) \(T_b\) is closer to the temperature of the reservoir that is connected through the cylinder of lower thermal conductivity

(D) \(T_b\) is closer to the temperature of the reservoir that is connected through the cylinder of higher thermal conductivity
