Solution
Correct Answer: Option C
- The chemical that is useful in photography is Silver bromide. -Silver bromide is a light-sensitive chemical that is used to coat photographic film and paper. When light hits silver bromide crystals, they are chemically changed. This change makes it possible to develop a latent image, which can then be fixed to create a permanent image.
