已知 $\alpha, \beta \in\left(0, \frac{\pi}{4}\right), \sin \alpha \cos \left(\frac{3 \pi}{2}+\alpha\right)-\sin \left(\frac{\pi}{2}+\alpha\right) \cos \alpha=-\frac{3}{5}$, 且 $3 \sin \beta=\sin (2 \alpha+\beta)$,则 $\alpha+\beta$ 的值为
A
$\frac{\pi}{12}$
B
$\frac{\pi}{6}$
C
$\frac{\pi}{4}$
D
$\frac{\pi}{3}$
E
F
