The correct answer is D. Small nations are less active in world trade.
Explanation
Oceania is a continent made up mainly of islands, among which Australia and New Zealand stand out internationally. However, the rest of the countries are very little known internationally and do not actively participate in trade because they do not have large industries, nor are they sources of natural resources. These islands are mainly considered tourist destinations for their tourist attractions. Therefore, the correct answer is D. Small nations are less active in world trade.
Tectonic plates are parts (pieces) of the outermost layer of Earth: the Crust. (the outermost part of the mantle is also often included in the plates). This means that the land in the middle of the plates is relatively stable while the borders of the plates can be in movement - after all this is where two pieces meet. Plate borders are where the vocanoes and Earthquakes often take place.
