The velocity vectors $\bar{V_{A}}$ and $\bar{V_{B}}$ shown in the figure

Question

A and B are the end-points of a diameter of a disc rolling along a straight line with a counter Clock-wise angular velocity as shown in the figure. Referring to the velocity vectors $\bar{V_{A}}$ and $\bar{V_{B}}$ shown in the figure                     

 

      (a) $\bar{V_{A}}$  and $\bar{V_{B}}$  are both correct

      (b) $\bar{V_{A}}$  is incorrect but $\bar{V_{B}}$  is correct

      (c) $\bar{V_{A}}$  and are both  incorrect

      (d) $\bar{V_{A}}$  is correct but $\bar{V_{B}}$ is incorrect
