Answer: The correct answer is Cultural diffusion.
Culture is defined as the characteristics of a particular group of people, which includes various aspects like their language, religion, social habits, dance, music, food. In simple words, it describes the way of living of a particular group of people.
Cultural diffusion is a process through which the cultural traits are passed from one society into another society. Through this process, people become culturally rich as their ideas and knowledge is broadened.
This process is accompanied through transportation, migration, advanced communication ( like using twitter, instagram, mass media etc.)
