Statement I : The Mediterranean climate is highly suitable for fruit production Statement II : Cool and moist winters in Mediterranean regions enable ample production of fruits.

Statement I is true as the Mediterranean region is famously known as the 'world's orchard lands' due to its high suitability for fruit production, particularly citrus fruits, olives, and grapes [2]. Statement II is also true and provides the correct explanation. The Mediterranean climate is characterized by hot, dry summers and cool, moist (rainy) winters [3]. These cool and moist winters are critical for fruit production because they provide the necessary 'winter chill' or chilling requirements that fruit trees need to break dormancy and bloom effectively in the spring [t1][t3]. Furthermore, the winter rains allow seeds to germinate and plants to grow steadily, while the mildness of the dark season facilitates the overwintering of vulnerable perennial fruit trees [1][t3]. Thus, the specific winter conditions are a foundational reason for the region's horticultural success.
