The process of splitting water molecule by light energy is calleda)Rad...

In a process called photolysis ('light' and 'splitting'), light energy and a catalyst interact to split water molecules into protons (H+), electrons and oxygen gas.
Option Explanation

Radiolysis is the separation of molecules by ionizing radiation. It is the cleavage of one or several chemical bonds as a result of exposure to high-energy currents.
Electrolysis , the process by which an electric current is passed through a substance to effect a chemical change.
Chemical decomposition occurs by heating thermolysis . If a reaction is endothermic, heat is required for the reaction to proceed.

important point

Photolysis is the process by which a photochemical reaction is conducted. The immediate result of light absorption is the primary photochemical reaction. Secondary reactions are called subsequent chemical changes.

confusing points _ _

Photolysis is defined as the decomposition of substances when exposed to light, whereas photooxidation is the oxidation of a substance when exposed to light.
Irradiation of tryptophan with UV light produces a tryptophan radical and a hydrated electron.
