  3. Glass 
  4. Wood

Hint:

Air, water and glass are transparent medium.

The correct answer is: Wood


    • When light ray goes from one transparent medium to another transparent medium it changes its path this phenomenon is called refraction .
    • Wood is an opaque object.
    • So, the correct option is d.
