General SciencePhysics
- ABoth the eyes see exactly the same image.
- BOne eye sees half portion of the object.
- CBoth the eyes combine the two images seen by them.
- DEach eye sees a slightly different image.
Explanation
Human vision is binocular — each eye views an object from a slightly different angle, producing two slightly different retinal images. The brain fuses this binocular disparity into a single three-dimensional perception (stereopsis), which gives depth perception. The eyes do not see exactly the same image, nor does each eye see only half the object. Hence (D) is correct.
