At certain temperature, $\operatorname{rod} \mathrm{A}$ and $\operatorname{rod} \mathrm{B}$ of different materials have lengths $\mathrm{L}_{\mathrm{A}}$ and $\mathrm{L}_B$ respectively. Their co-efficients of linear expansion are $\alpha_A$ and $\alpha_B$ respectively. It is observed that the difference between their lengths remain constant at all temperatures. The ratio $L_A / L_B$ is given by

A
$\frac{\alpha_A}{\alpha_B}$
B
$\frac{\alpha_B}{\alpha_A}$
C
$\frac{\alpha_A+\alpha_B}{\alpha_A}$
D
$\frac{\alpha_A+\alpha_B}{\alpha_B}$
