Correct Answer

D

Explanation

The photochemical reaction among the options is the "Conversion of silver halides to grey metallic silver." Photochemical reactions involve the absorption of light to initiate a chemical change. In this case, silver halides (such as silver bromide or silver chloride) are sensitive to light, and exposure to light causes them to undergo a photochemical reaction, resulting in the formation of grey metallic silver. This process is commonly used in photography, where silver halide crystals in film or photographic paper are exposed to light to capture images.
