Two masses $$M_1$$ and $$M_2$$ are arranged as shown in the figure. Let $$a$$ be the magnitude of the acceleration of the mass $$M_1$$. If the mass of $$M_1$$ is doubled and that of $$M_2$$ is halved, then the acceleration of the system is (Treat all surfaces as smooth; masses of pulley and rope are negligible)

A
$$\left(\frac{M_1+M_2}{4 M_1+M_2}\right) a$$
B
$$\left(\frac{2 M_1+M_2}{4 M_1+M_2}\right) a$$
C
$$\left(\frac{M_1+2 M_2}{4 M_1+2 M_2}\right) a$$
D
$$\left(\frac{M_1+2 M_2}{M_1+M_2}\right) a$$
