Model Answer

(B) Black and white photography

Explanation

Silver chloride (AgCl) decomposes into silver metal and chlorine gas in sunlight — this photochemical reaction is the basis of black and white photography, where silver deposits form the image. This is a standard example from Chapter 1/Chapter 3 of NCERT Science Class 10.
