The answer is I. One of the reasons that people of the 18th century wrote travel narratives was to help create business relationships with other cultures.
Travel narratives were commonly writen by europeans, who wrote about distant lands and their population; this genre responded to the public's growing interest for knowledge of the world. It was this knowledge that made the creation of business relationships possible, travel narratives gave accounts of other people's culture, traditions and values, but they also gave an account of what other cultures, in terms of products, had to offer to a growing international market.
