Answer:
The correct answer is letter "D": context.
Explanation:
American anthropologist Edward Hall (1914-2009) in his book "The Silent Language" analyzed intercultural communication. According to Hall, intercultural communication is the share of information between individuals of different cultures.
Hall defined context as the complexity a message carries to be understood. Thus, high-context cultures are those in which a great knowledge is necessary to understand the language (Chinese, African, or Arab) and low-context cultures are those in which communication is explicit (German, English or Italian).
