The temperature of the rods is increased by `DeltaT` and correspondingly the change in their respective lengths be `DeltaL_(1)` and `DeltaL_(2)`

A

`DeltaL_(1)!=DeltaL_(2)`

B

`DeltaL_(1)=DeltaL_(2)`

C

Difference in length `(L_(1)-L_(2))` is a constant and is independent of rise of temperature.

D

Data in insufficient to arrive at a conclusion
