Answer

It must be directly above the stilt.

Work Step by Step

If the person's center of mass was not directly above the stilt, then a net torque would be present, causing her to rotate. Thus, if she remains in an upright position, then she must be directly over the point where the stilt comes in contact with the ground, meaning that she theoretically will not rotate.
