Which of the following choices represents the top nations for per capita emission of carbon dioxide?

The top nations for per capita emission of carbon dioxide are accurately represented by Australia, the United States, and Canada. These countries have relatively high levels of carbon dioxide emissions per person due to a combination of factors such as their energy consumption patterns, reliance on fossil fuels, industrial activities, and overall economic structures.

Australia, for example, has a significant portion of its energy generated from coal, contributing to high emissions. The United States, being one of the largest economies in the world, has substantial energy needs and historically high emissions due to transportation, industry, and electricity generation. Canada has a vast land area and high energy consumption per capita as well, primarily driven by its resource extraction industries and energy-intensive economy.

In contrast, the other choices consist of countries that, while having high total emissions, do not rank as high on a per capita basis. For instance, China and India have large populations, which means their total emissions are significant, but when measured per individual, they rank lower than Australia, the United States, and Canada. Similarly, Germany, France, Japan, Russia, South Korea, and Mexico have varying emissions profiles that do not reach the same per capita levels recorded in the top three nations.
