The correct answer is **a) carbon dioxide, only**.
During a 24-hour period, green plants continuously require and use carbon dioxide for the process of photosynthesis, which occurs mainly during daylight hours. While they also produce oxygen as a byproduct of photosynthesis, they primarily need carbon dioxide for this process. At night, plants do consume oxygen during respiration but the main substance they continuously require for photosynthesis is carbon dioxide.
