The answer choices are not provided, so I cannot select the correct one. However, I may provide you examples and guidance on how to choose the correct one.
As mentioned in the explanation, a scientific question must have a variable that is changed, the independent variable, and a variable on which the effect of the change is measured. This is the dependent variable. Examples of such questions include:

How will the amount of water given to a plant affect its rate of growth?
What will be the amount of sugar that can be dissolved in water at a given temperature?
At what temperature will a balloon filled with air pop?

All of these questions may be tested using experiments.

Answer: Carbohydrates in the form of glucose and oxygen as byproduct.

Explanation:

Photosynthesis is a process which occurs in green plants and in other autotrophs. In this process the autotrophs can prepare their own food by using reactants like water and carbon dioxide to produce glucose which is a carbohydrate which a major source of energy for plants and oxygen gas is released as a byproduct of this chemical reaction. On the contrary to this the cellular respiration can be defined as the process in which the biochemical oxidation of food occurs and energy is released in the form of ATP and carbon dioxide and water are produced.

Thus in photosynthesis the carbon dioxide and water are the reactants whereas in cellular respiration they are the products.
