1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
This is a solved question. The answer is given above.
I can't understand why h1=h2.

Assume that $T_C$ is between $T_A$ and $T_B$ and that there are equal heat flow rates $B \rightarrow C$ and $C \rightarrow A$ (because we want to calculate steady-state temperatures, and without the equality of the rates the $T_C$ would be changing).

H = heat flow. Heat H1 flows down B->C. The problem says to assume only conduction (eg through the rods) no radiated losses so where else can that heat flow go if not down C->A ? Therefore H1=H2.
