* Light Dependent Reactions: This is the first stage of photosynthesis. It directly uses sunlight to:

* Split water molecules (photolysis) into hydrogen ions (H+), electrons (e-), and oxygen (O2).

* Use the energy from light to create ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate).

Let's look at the other options:

* (b) Independent: This refers to the Calvin cycle, the second stage of photosynthesis, which doesn't directly use light.

* (c) Carbon Fixation: This is a part of the Calvin cycle where carbon dioxide from the atmosphere is incorporated into an organic molecule.

* (d) Photophosphorylation: This is the process of using light energy to generate ATP, a key part of the light-dependent reactions.

* (e) Glyc?: This likely refers to glycolysis, which is part of cellular respiration, the opposite of photosynthesis.

In summary: The splitting of water to release hydrogen ions and electrons is a critical part of the light-dependent reactions of photosynthesis.
