Answer:

D. Silver bromide​

Explanation:

Silver bromide (AgBr) is used in photographic films because silver bromide is light sensitive.

Silver bromide (AgBr) is a colorless coating on a photographic film that decomposes and converted to elemental silver when exposed to the light and causes the film to darken.

Hence, the correct answer is "D. Silver bromide​".
