Two rods, one of aluminium and the other of steel, having initial lengths ' $\mathrm{L}_1$ ' and ' $\mathrm{L}_2$ ' are connected together to form a single rod of length $\left(L_1+L_2\right)$. The coefficients of linear expansion of aluminium and steel are ' $\alpha_1$ ' and ' $\alpha_2$ ' respectively. If the length of each rod increases by the same amount, when their temperatures are raised by $\mathrm{t}^{\mathrm{L}} \mathrm{C}$, then the ratio $\frac{L_1}{L_1+L_2}$ will be

A
$\frac{\alpha_2}{\alpha_1}$
B
$\frac{\alpha_1}{\alpha_2}$
C
$\frac{\alpha_2}{\alpha_1+\alpha_2}$
D
$\frac{\alpha_1}{\alpha_1-\alpha_2}$
