Two rods of length `L_(1)` and `L_(2)` are made of materials of coefficients of linear expansions `alpha_(1)` an `alpha_(2)` respectively such that `L_(1)alpha_(1)=L_(2)alpha_(2)`. 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 ne DeltaL_2`

B

`DeltaL_1 =DeltaL_2`

C

The difference in the length `(L_1 -L_2)` is a constant and is independent of the rise of temperature

D

Data insufficient to arrive at a conclusion.
