Vedclass · Answer

(D) Photography relies on the photosensitivity of silver halides,particularly $AgBr$,which decomposes upon exposure to light. Sodium thiosulphate $(Na_2S_2O_3)$ is used as a 'fixing' agent to dissolve and remove the unexposed $AgBr$ from the film,preventing further darkening. $AuCl_3$ (gold chloride) is used in the process of toning to improve the image quality and stability. Therefore,all the given statements are correct.
