      Splitting of water is associated with (a) photosystem I                                                            (b)lumen of thylakoid (c) both photosystem I and II                                     (d) inner surface of thylakoid membrane

    Answer:

                      (d) The thylakoid is a photosynthetic unit in the chloroplast. It is a membrane bound structure. The membrane has photosystems I and II embedded in it, in the form of chemicals and molecules.
