The nation that sustained a communist revolution in the years immediately after World War II is China. To arrive at this answer, one can utilize a basic understanding of history or conduct a quick search using a reliable source, such as an online search engine or history reference material.

First, let's analyze each option and eliminate the ones that are not correct:

- Afghanistan did not experience a communist revolution in the years following World War II. While Afghanistan has had periods of political upheaval throughout its history, such as the Soviet invasion in 1979, it did not go through a communist revolution after World War II.

- Japan also did not undergo a communist revolution after World War II. Instead, Japan experienced significant political and societal changes during this time under occupation forces led by the United States.

- Russia, or the Soviet Union as it was known during World War II, was already a communist nation before the war and did not go through a revolution immediately following it.

This leaves us with China as the only remaining option. China experienced a communist revolution led by Mao Zedong and the Chinese Communist Party, which eventually led to the establishment of the People's Republic of China in 1949. This revolution happened directly after World War II and resulted in sweeping political and social changes in the country.
