D)-90 and 180 degrees.

Question

Quizplus · Accepted Answer

An indeterminate axis is the line of an object that has an undefined direction of rotation about that axis. This occurs when the object has symmetry in its shape along that axis. For example, a cylinder has an indeterminate axis that lies along its central axis. The angle of rotation about this axis can be any angle between -90 degrees and +90 degrees, as flipping it upside down or rotating it by 180 degrees would result in the same orientation. Thus, the correct answer is option D, which covers the range of angles from -90 to 180 degrees.
