B
$$\frac{3 \mathrm{~V}}{2}$$
C
$$3 \mathrm{~V}$$
D
$$6 \mathrm{~V}$$

In a medium, the phase difference between two particles separated by a distance '$$x$$' is $$\left(\frac{\pi}{5}\right)^{\text {c }}$$. If the frequency of the oscillation of particles is $$25 \mathrm{~Hz}$$ and the velocity of propagation of the waves is $$75 \mathrm{~m} / \mathrm{s}$$, then the value of $$x$$ is

A
0.4 m
B
0.1 m
C
0.2 m
D
0.3 m
