d. china and japan

The correct answer is B. As of 2010, both China and India had populations exceeding one billion people.

The 2010 national census recorded that the population of the People's Republic of China was of 1,370,536,875 inhabitants. Although China is the most populous country in the world, its national demographic density (137 / km2) is not very high, but similar to those of Switzerland and the Czech Republic. The overall population density of the People's Republic of China does not show the important regional variations: the western and northern part have a few million inhabitants, while the eastern part has about 1.3 billion. The vast majority of the Chinese population lives in the fertile plains of the east.

By 2010, India had a population of 1,100,000,000 inhabitants; it also had 35 cities with more than one million inhabitants, while the three largest cities (Bombay, Delhi and Calcutta) had more than ten million inhabitants each.
