Hint: Photosynthesis is the process in which green plants prepare their own food and also produce food to other organisms that depend on them using water, carbon dioxide with the help of sunlight and chlorophyll. In this process, the carbon dioxide is utilized and oxygen is released.
Complete answer:
In the photosynthesis process, the light energy from the sun is converted into the chemical energy that is used for plant growth. The water absorbed by the root is spitted into the protons and the oxygen molecule by the process of photolysis. Photolysis is the process in which the water is broke into the other compounds in the presence of sunlight. It mainly takes place in the presence of light. The chlorophyll in the chloroplast absorbs the sunlight. The obtained oxygen is released to the outer environment which in turn is used by all the other organisms for respiration.
$6C{O_2} + 6{H_2}O \to {C_6}{H_{12}}{O_6} + 6{O_2}$
The above reaction is the photosynthesis reaction in which the carbon dioxide and water in the presence of sunlight converts into the glucose sugar and the oxygen. Hence, the source of oxygen liberated during the process of photosynthesis is water.
Hence, the correct answer is Option (C)
Note: Photosynthesis mainly occurs in the chloroplast. It is also known as plastid. The end product of the photosynthesis is sugar and the obtained sugar is converted into starch and stored. In chloroplast, the thylakoid membrane is there, into which the starch is stored in the stroma.
