Which statement correctly defines hot climate?

Explanation:
Growing Season Temperature (GST) is the measure used to classify climates for grape growing, based on the average air temperature during the period when grapes ripen. A hot climate is defined by GST in excess of 21°C (about 70°F). This threshold signals a warmth level that generally accelerates ripening and sugar accumulation, affecting balance, acidity, and flavor development in grapes. The option stating GST above 25°C is not the standard boundary used here, while the 15–18°C range describes cooler conditions, not hot. Rainfall amount does not define the hot climate category in this framework.
