The correct answer is - II and III.
The agribusiness has been helping a lot to the people in the developing countries around the world, mostly with better food supply and the support in the traditional agricultural practices.
The better food supply comes from the proper distribution of the food on the home markets, and it is also food that is produced in the country, not imported one, so everyone sees the benefit from it.
The support in the traditional agricultural practices is also very important, as the farmers are managing to get easy access to the things they need for farming, but also they have secured market for their products. The traditional agricultural practices are also supported as in those ways it is possible to produce organic food, for which there's an ever growing market.
