During photosynthesis, the light-dependent reactions in the chloroplast produce ATP, NADPH, and O$_2$. Of these, oxygen (O$_2$) diffuses out of the chloroplast as a byproduct. ATP and NADPH are used within the chloroplast to drive the light-independent reactions (Calvin cycle), which produce sugars.
Which of the following is responsible for the production of oxygen during photosynthesis?
A. Calvin cycle
B. Photolysis of water
C. Cyclic photophosphorylation
D. Reduction of NADP+
