C. is always perpendicular to the surface of the conductor

Explanation:

On a charged conductor, electric charge is uniformly distributed on its surface. The lines of forces are also uniformly distributed on all directions. They repel each other so they emerge perpendicular to the surface so that they do nor cut each other and at the same time they remain at maximum distance from each other.
