The circular disc shown in its plan view in the figure rotates in a plane parallel to the horizontal plane about the point $$O$$ at a uniform angular velocity $$\omega$$. Two other points $$A$$ and $$B$$ are located on the line $$OZ$$ at distances $${r_A}$$ and $${r_B}$$ from $$O$$ respectively.

The velocity of point $$B$$ with respect to point $$A$$ is a vector of magnitude

A
$$0$$
B
$$\omega \left( {{r_B} - {r_A}} \right)$$ and direction opposite to the direction of motion of point $$B$$
C
$$\omega \left( {{r_B} - {r_A}} \right)$$ and direction same as the direction of motion of point $$B$$
D
$$\omega \left( {{r_B} - {r_A}} \right)$$ and direction being from $$O$$ to $$Z$$
