  • B
    Between eye lens and retina
  • C

  • D

✓

Answer

  1. Beyond retina

Explanation:

A defective eye cannot see close objects clearly because its image is formed beyond the retina.

This defect is known as farsightedness.

Here rays from near objects could not be converted at the retina due to focal length of the eye lens could not be decreased, so, image is formed beyond the retina.
