A solid cylinder is rolling down an inclined plane without slipping. At any given instant, the velocity of the point of contact of the cylinder with the plane is:

1. A
   Equal to the velocity of the centre of the cylinder.
2. B
   Twice the velocity of the centre of the cylinder.
3. C
   Dependent on the inclination angle \( \theta \) and always positive.
4. D
   Zero.
