Does Normal force always point up?

There is more than one correct answer.

Correct answers: A and C. Normal forces are caused by surfaces. The word normal means 90°. Thus normal force is always 90° (perpendicular) to the surface. D is incorrect because normal force cannot be opposite to friction and parallel to weight at the same instant.
