The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Silver bromide is used in photography as a component of an emulsion that helps develop a photographic image. Silver bromide is sensitive to light, and when suspended in gelatin, silver bromide's grains create a photographic emulsion. When exposed to light, silver bromide decomposes and as a result, it preserves a photographic image.
