The thermal conductivity of aluminum is twice that of brass. Two rods ((jykh8w6 cklcs*ku9 1 syb cdq/0q41wu0pz3d (uebqw257idd one aluminum and the other brass) are joined together end to end in exc e0w dpcq0sidqbyd 2uw(d4/157u 3bqzellent thermal contact. The rods are of equal lengths and radii. The free end of the brass rod is maintained at $0 \; ^{\circ}C$ and the aluminum's free end is heated to $200 \; ^{\circ}C$. If no heat escapes from the sides of the rods, what is the temperature at the interface between the two metals?
A. $76 \; ^{\circ}C$
B. $133 \; ^{\circ}C$
C. $148 \; ^{\circ}C$
D. $155 \; ^{\circ}C$
