Answer
Both A and R are true and R is the correct explanation of A.
Reason — A is true as green plants are autotrophs, meaning they make their own food through photosynthesis. They use carbon dioxide (from air) and water (from soil) as raw materials.
R is true as Chlorophyll (present in chloroplasts) and sunlight are essential for photosynthesis, but they are not raw materials. Instead, they act as conditions or energy sources needed for the process.
Therefore, Both A and R are true and R is the correct explanation of A is the correct option.
