The Calvin cycle is the pathway by which plants produce sugar using carbon dioxide, water, and energy from sunlight. If an herbicide blocked the cycle before the generation of G3P, which is a key component in the production of sugar, then the plant would not be able to make sugar. Therefore, option C is the correct answer. Option A is incorrect because blocking the cycle before G3P would completely prevent sugar production, not just reduce it. Option B is incorrect because the release of oxygen is not directly related to the generation of G3P. Option D is incorrect because other compounds in the cycle, such as PGA, would also not be recycled.
