Consider a wheel
Looking into fig, we can say that points B, C and D cannot have equal speeds, because the wheel is not
in pure rotation about O. Hence, option (B) becomes false.
It can be seen that diameter of the wheel, AC is instantaneously in pure rotation about the point A. So, the speed of the particle A is zero. Option (A) is true
The point B has one more component of velocity downward, hence its total velocity > velocity of O.
Hence option (D) also correct.
Also, speed of point C remains since its moving along the axis of wheel.
