The photosynthesis is consists of two biological reaction systems are light dependent and light independent reactions. The CO\\\\(_2\\\\) is fixed in this system.The plant uses light energy to generate NADPH and ATP. The chemical bonds in these compounds store the energy and are used during the light independent phase.The light independent phasen the ATP and NADPH generated in the light phase utilised to make C-C bonds of carbohydrates from carbon dioxide and water, with the RuBP. Six molecules of carbon dioxide enter the cycle, which in turn produces one molecule of glucose or sugar.So, the correct answer is option A.
