Temperature difference of 120^{0}C^{ }is maintained between two ends of a uniform rod AB of length 2L. Another bent rod PQ, of same cross-section as AB length , is connected across AB(See figure). In steady state, temperature difference between P and Q will be close to:

a. |
60 |
b. |
75 |

c. |
35 |
d. |
45 |
