Answer: Choice A. It has rotational symmetry about the origin.
Rotational symmetry about the origin means the point (x,y) on the function curve rotates to (-x,-y) which is also on the curve as well.
For instance, the point (2,8) is on the odd function f(x) = x^3, and so is the point (-2,-8).
Going from (2,8) to (-2,-8) is a rotation of 180 degrees around the origin.
If f(x) is an odd function, then f(-x) = -f(x) for all x in the domain.
