Answer: (B)

Verified step by step guidance

1. Identify the function of the lens in the human eye. The lens is a transparent structure located behind the iris and pupil.
2. Understand that the primary role of the lens is to focus light onto the retina. It does this by changing its shape, a process known as accommodation.
3. Differentiate the lens from other parts of the eye, such as the retina, which is responsible for receiving light and sending visual information to the brain.
4. Recognize that the lens does not change size based on light; this function is performed by the pupil, which adjusts to control the amount of light entering the eye.
5. Conclude that the statement 'It changes shape to bring objects into focus' accurately describes the function of the lens, as it adjusts its curvature to focus light on the retina for clear vision.
