The process of splitting water to release hydrogen ions and electrons occurs during the process.

Light dependent is the correct answer.

The process of splitting water occurs during the light dependent process. Specifically, water is split to yield hydrogen ions, electrons, and oxygen. The hydrogen ions and electrons are used to generate ATP and NADPH. Oxygen is a by-product of these reactions, although it is essential to most forms of life.
