Why is photorespiration more likely to occur in warm weather?

• A) Plants require warm weather (at least 23°C) to drive photosynthesis.
• B) Plants are more likely to close their stomata in the daytime heat than at night when it is cool.
• C) Plants are more likely to dehydrate in warm weather, forcing them to close their stomata to conserve water; this prevents CO₂ from entering the leaf.
