The correct Answer is:
To determine which potted plant will show flowering after exposure to light, we need to analyze the light exposure of each plant in relation to the critical photoperiod for a short day plant, which is 14 hours. ### Step-by-Step Solution: 1. **Identify the Critical Photoperiod**: - The critical photoperiod for the short day plant is 14 hours. This means that the plant will flower only when it receives light for less than 14 hours. 2. **Review the Light Exposure of Each Plant**: - Plant I: 10 hours - Plant II: 15 hours - Plant III: 16 hours - Plant IV: 20 hours 3. **Compare Each Plant's Light Exposure to the Critical Period**: - Plant I (10 hours): This is less than 14 hours, so it is suitable for flowering. - Plant II (15 hours): This is more than 14 hours, so it will not flower. - Plant III (16 hours): This is also more than 14 hours, so it will not flower. - Plant IV (20 hours): This is significantly more than 14 hours, so it will not flower. 4. **Conclusion**: - Only Plant I, which has been exposed to light for 10 hours, meets the criteria for flowering since it is below the critical period of 14 hours. Therefore, Plant I will show flowering after exposure to light. ### Final Answer: - The potted plant that will show flowering after exposure to light is **Plant I**.
