Answer 1

Answer: (A), (B), (C)

Indigenous varieties of an area are native varieties that are naturally found in that particular area. They acquire natural immunity by adapting to the climate, availability of food and soil texture of that place. Indigenous varieties have high resistance to diseases prevalent in the particular area. Large-scale introduction of hybrid varieties is resulting in the extinction of indigenous species. A rich biodiversity is very important as the existence of many different types of plants and animals makes the world a healthier and more productive place.
