Answer:

Option: A. The population grew with the introduction of new crops, enhancing diets and elevating life expectancy.

Explanation:

Prior to European contact, the New World was home to Indigenous people. The arrival of Christopher Columbus marked the start of the Colombian Exchange, bringing new plant and animal species to the Old World. The discovery of a resource-rich area transformed trade dynamics between Europe and the New World, leading to the introduction of various agricultural products such as tomatoes, pumpkin, potatoes, chillies, cocoa, maize, peanuts, and beans. The influx of these new nutrients, which were both calorie-rich and flavorful, contributed to an enhanced life expectancy.

The integration of these new foods facilitated population growth in Europe. In particular, maize substituted for rye and millet, while sweet potatoes gained popularity in Spain and Portugal, eventually becoming a staple in Ireland and Poland. Compared to traditional cereals, the new crops provided greater nutritional value.
