The correct answer is C.
The Internet has made American culture more accessible to the rest of the world because of its broad usage. Nowadays, most information about everything is taken off the Internet and it is by far the most used source of knowledge. Citizens of many countries are not allowed to travel freely to the USA as they require entry visas. They would not be able to gather any info about American culture first-hand and Internet is the only way to obtain some insight into the culture. This is done by listening to American music, watching American movies and documentaries, reading American newspapers and engaging and participating in online chats with people from the United States.
