Final answer:
Farmers aiming to breed a more nutritious potato would likely breed two nutritious potato species together to combine beneficial traits, leveraging genetic diversity. So the correcct option is B.
Step-by-step explanation:
When farmers want to create a more nutritious form of potato, they would most likely choose two nutritious species of potatoes to breed. This option, breeding for agricultural diversity, is crucial for enhancing nutrition and ensuring food security. By crossing two nutritious varieties, they maximize the chance of combining beneficial traits to produce offspring with improved nutritional value. The process of creating new crop varieties leverages the genetic diversity found within and between species, which is essential for introducing new traits such as increased nutritional value, adaptation to growing conditions, and resistance to pests. This practice has been a cornerstone of human agriculture for over 10,000 years.
