Final answer:

Oxygen production during photosynthesis occurs during light-dependent reactions and involves photosystem two (PSII) and the splitting of water, but not photosystem one (PSI). The correct option is b.

Step-by-step explanation:

Oxygen production in photosynthesis involves all of the following EXCEPT photosystem one. The process of oxygen production takes place during the light-dependent reactions of photosynthesis. In these reactions, photosystem two (PSII) plays a critical role by using light energy to split water molecules (photolysis), releasing oxygen, protons, and electrons. The electrons are then transferred to photosystem I (PSI) through an electron transport chain. PSI primarily functions to facilitate the conversion of NADP+ to NADPH using light energy and does not directly split water to generate oxygen.
