Let $\alpha$ and $\beta$ respectively be the maximum and the minimum values of the function $f(\theta)=4(\sin^{4}(\frac{7\pi}{2}-\theta)+\sin^{4}(11\pi+\theta)) - 2(\sin^{6}(\frac{3\pi}{2}-\theta)+\sin^{6}(9\pi-\theta))$, $\theta \in R$. Then $\alpha+2\beta$ is equal to:

  • A
    $4$
  • B
    $5$
  • C
    $3$
  • D
    $6$
