The correct answer is - I, III, and IV.
There's multiple reasons why the organic production is pretty rare throughout the world, like the expensive production, specific tools, more effort, more losses of the products, not enough education etc.
The organic production is much harder than the conventional one, as everything has to be natural, without the usage of any chemicals for protection, and using specialized tools. Also, bug problem are the pests, as the plants can be properly protected so the losses are much bigger.
This type of products are also not in high demand, and the reason for that is their price. While there is a trend in the Western World for increased consumption of organic food, the reality is that most of the people can not afford it even in the highly developed countries, while the consumption in the less developed countries is almost non-existent.
The process of production of this type of food also requires education, as it is not very simple, nor is the same as the conventional production, and most of the people do not have that education.
