(A) The human eye is in a relaxed state when it is focused on objects at infinity. In this state,the ciliary muscles are least strained,and the focal length of the eye lens is at its maximum. As the object moves closer to the eye,the ciliary muscles must contract to increase the curvature of the lens,thereby decreasing the focal length to maintain focus on the retina. Therefore,the strain on the ciliary muscles is minimum when the object is at infinity.

When the human eye is focused on an object,the ciliary muscles are least strained when the object is at:
