A substance undergoes first order decomposition. The decomposition follows two parallel first order

Question

A substance undergoes first order decomposition. The decomposition follows two parallel first order reactions as where $\mathrm{k}_{1}=2 	imes 10^{-4} \mathrm{~s}^{-1}$ and $\mathrm{k}_{2}=4 	imes 10^{-4} \mathrm{~s}^{-1}$. The correct relation/s relevant to the above reaction is/are\

Overall rate of reaction $=\left(k_{1}+k_{2}ight)[A]$\ and ratio of the yields, $\frac{[\mathrm{B}]}{[\mathrm{C}]}=\frac{\mathrm{k}_{1}}{\mathrm{k}_{2}}$ at\ any stage of the reaction\
