Your question has a fault. The United States is no longer the country with the highest amount of internet users. As of 2018. China has taken the top spot with around 770 million internet users followed by India with 500 million. The USA sits at third with around 350 million. It's funny how cheap internet affects a country's internet usage.
After the United States and China, the country with a large number of internet users would have to be letter D. or Japan. Japan is known to be one of the most disciplined countries in the world when it comes to following rules and regulations. A lot of people’s choices there are largely affected by their “honor.”
They pay close attention to the things that they should do so that they will not ruin their family name wherever they go. Even with this type of culture, a lot of Japanese are lovers of high-tech gadgets and devices. They love going online for different reasons. There are an estimated 118 million users of the internet in Japan which is far more than the other countries on the list.
The answer to this is Japan. The culture of Japan has changed significantly over the past years but the fact still remains that they have high regard for their culture. There are some things about their culture that have withstood the test of time. There are still some places wherein you can find real-life geishas.
You can still find a lot of television shows, movies, and so much more that depict their history and their modern lives. It is no wonder that there are a lot of internet users from Japan because they have a very high-tech system there. They have advanced appliances that are not available in other parts of the world.
Out of the given choices, the answer to the question which country follows the United States and China in total number of Internet users is letter D or Japan.
