Answer: (c)

The light dependent production of ATP from ADP + Pi in the chloroplasts is called photophosphorylation. Photophosphorylation is of 2 types – Cyclic photophosphorylation – It involves only PS-I, water is not utilised and so no oxygen is evolved. Here two ATP molecules are produced. Non-cyclic photophosphorylation – It involves both PS-I and PS-II, water is utilised and so oxygen is evolved. Here one ATP molecule and one $NADPH_2$ molecule are produced.
