Which of the following statements about photosynthesis is FALSE?

A) The light reactions occur within or on the thylakoid membranes.
B) The dark reactions occur in the stroma of the chloroplast.
C) The light reactions oxidise water to oxygen, reducing NADP+ to NADPH in the process.
D) The dark reactions use the NADPH and ATP formed in the light reactions in reductive synthesis of carbohydrate from CO2 and water.
