System of Particles and Rotational Motion Report Error

Solution:

For pure rolling the bottom most point will remain at rest hence option (A) is correct. In every point of wheel there will be two speeds , one due to translational motion in forward direction and other due to rotational motion along tangential direction so speed of any point is the vector sum of these two hence option (C) and (D) is correct.
