is the difference between the two retinal images of the same scene, and is the basis of stereopsis.

Binocular disparity

Explanation:

Stereopsis is one of the abilities of the eye which allows it to look into the depth and details of the formed image in the brain that allows us to see the 3D image.

The basis of the formation of the Stereopsis is the 'binocular disparity" caused due to the ability of the two left and right eyes to form two different images at a different angle.

The left and right eye form two different 2D images of the specimen on the retina. When these two 2D images are combined by the brain allows us to look into the depth of the image.

Thus, Binocular disparity is the correct answer.
