(D) Herbicides are chemical substances used to control or kill unwanted plants (weeds). Many herbicides,such as $DCMU$ ($3$-($3$,$4$-dichlorophenyl)$-1,1-$dimethylurea),act by blocking the electron transport chain in photosynthesis. Specifically,they inhibit the photolysis of water,which is the light-dependent splitting of water molecules. Since the photolysis of water is responsible for the release of $O_2$ during photosynthesis,its inhibition directly leads to the inhibition of $O_2$ evolution. Furthermore,some herbicides interfere with the metabolic processes required for the translocation of organic solutes (sugars) through the phloem. Therefore,all the listed options are recognized effects of various types of herbicides.
