Answer:
D. magnetic polarity reversals
Explanation:
The marine magnetic anomalies are the result of two things; the seafloor spreading at the mid-ocean ridges and the magnetic polarity reversals.
The mid-ocean ridges are the places where the new crust forms. This places also have big influence on the magnetic anomalies, with the reason being that the magnetism has higher influence in this parts.
Also, the magnetic polarity reversals play a big role. The Earth has not always had the same magnetic polarity, and multiple times throughout its past the North and South Poles have been switching places when it comes to the magnetism.
The igneous rocks on the ocean floor have proof in them about this, as the metallic components are reacting to the magnetism and face toward the stronger magnetic field.
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.
