A
Water
B
Sunlight
C
Soil
D
Carbon dioxide
Explanation: 

Detailed explanation-1: -Photosynthesis is the process of synthesis of food by plants using carbon dioxide and water in presence of sunlight and chlorophyll. Oxygen (O2) is released during the process as a waste product. Hence, oxygen is not essential for the process of photosynthesis.

Detailed explanation-2: -So, the correct answer is ‘Iodine solution’.

Detailed explanation-3: -If you said that plants get their nutrients and water from the soil, you are right! Although all green plants make their food by photosynthesis, they also need to get nutrients from the soil. These dissolve in water and are taken up by the roots of the plant.

Detailed explanation-4: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-5: -Final step: Oxidation of carbon to carbon dioxide doesn’t occur during photosynthesis.
