Correct Answer: method of breeding crops to increase their nutritional value

Solution : The correct option is method of breeding crops to increase their nutritional value.

Biofortification is the process of breeding crops to increase their nutritional content, especially vital elements like vitamins and minerals. By developing varieties of crops with greater quantities of minerals such as iron, zinc, vitamin A, and others, this technique tries to solve nutritional shortages and promote public health. Biofortified crops can help reduce hunger, particularly in areas where diets lack vital nutrients. Golden Rice, for example, has been genetically engineered to include beta-carotene, a precursor of vitamin A, in order to address deficiency of vitamin A.
