Solution
The correct option is A Photosynthetic bacteria
The substance/gas produced at the end of photosynthesis depends on the electron donor split at the begining of the reaction.
In most organisms like red algae, blue-green algae and C4 plants electrons for the electron transport chain are obtained by the splitting of water and oxygen acts as a final acceptor of electrons causing its release after the process.In photosynthetic bacteria, other compounds like hydrogen sulphide is used as an oxygen donor leading to production sulphur.The correct answer is 'photosynthetic bacteria'.
