Best answer

Answer: 1. ligaments attached to the ciliary body

Key idea: The lens is suspended by the suspensory ligaments (zonular fibres).

These ligaments run from the lens edge to the ciliary body. The ciliary muscles change the tension on them and so change the lens curvature for focusing. The iris is a separate structure that controls pupil size and does not hold the lens.

Answer: option 1.
