Solution

The correct option is A $O_{2} / C O_{2} = 1$
The growth of plants is accompanied by an increase in their carbon content. During the photosynthesis, plants intake carbon dioxide and use as carbon source for synthesis of carbohydrates. During this process oxygen is released. The below equation indicates that the ratio of oxygen release and carbon dioxide intake is 1 : 1.
