Which process in the light-dependent reactions results in the release of hydrogen ions, electrons, and oxygen?

The question lacks options, the options are:

A) chemiosmosis B) photophosphorylation C) water splitting D) electron transport

The answer is C

Explanation:

Photosynthesis, which is the synthesis of carbohydrates, occurs in two stages in the Chloroplast of plant cells. The processes are light dependent stage and light-independent stage.

The light dependent stage involves Chlorophyll pigments called PHOTOSYSTEMS (I and II), which gets struck by a photon of light to become excited or activated. The energy in this excited Chlorophyll causes water molecule (H2O) to split in a process called PHOTOLYSIS, into oxygen molecule, two hydrogen ions (H+) and two electrons.

The electron is then transferred in an Electron transport chain to eventually yield ATP and NADPH molecules.
