Question

The energy released in this process was originally present in

Answer 1

I think your question is: The energy released during this process was originally present in 
(1) sunlight and then transferred to sugar 
(2) sunlight and then transferred to oxygen 
(3) the oxygen and then transferred to sugar 
(4) the sugar and then transferred to oxygen

The right answer is (1)
The sunlight is absorbed by chlorophyll as an energy to catalyse the formation of ATP and 3-phosphoglycerate to form sugar (which is considered as energy supply.

Answer 2

The complete question is :

The energy released during this process was originally present in 

(1) sunlight and then transferred to sugar 

(2) sunlight and then transferred to oxygen 

(3) the oxygen and then transferred to sugar 

(4) the sugar and then transferred to oxygen

Answer: Option A

Explanation:

The process of photosynthesis primarily needs sunlight to takes place. The carbon dioxide and water is combined in the presence of sunlight to get converted into sugar and oxygen is released as the by product of this process.

The energy from the sun is being converted into chemical form. Sugar from the leaves is stored in different parts of the plants.

The sugars in the plant is stored in the form of starch and is used when the the energy is required by the plant body.
