A particle moves along a straight line, such that its displacement $x$ varies with time $t$ as $x=\alpha t^3+\beta t^2+\gamma$, where $\alpha, \beta$ and $\gamma$ are constants, $v_1$ is the average velocity of the particle during its journey between $t=1 \mathrm{~s}$ and $t=3 \mathrm{~s} . v_2$ is the instantaneous velocity of the particle at $t=3 \mathrm{~s}$. The ratio $\frac{v_1}{v_2}$ is

A

$\frac{27 \alpha+9 \beta}{26 \alpha+6 \beta}$

B

$\frac{9 \alpha+3 \beta}{18 \alpha+4 \beta}$

C

$\frac{13 \alpha+4 \beta}{27 \alpha+6 \beta}$

D

$\frac{26 \alpha+8 \beta}{9 \alpha+3 \beta}$
