According to a different source, these are the options that come with this question:
A. Mandarin had replaced Cantonese as the primary spoken language in southern China.
B. Migrations and commercial contacts led to the use of printing in southern China.
C. Portuguese merchants had established trading posts in southern China.

The main reason why the Portuguese merchants and explorers were able to communicate with the local population of Canton was because the Portuguese had already established trading posts in Southern China. This meant that many explorers and merchants were already well-acquainted with Chinese people. The first Portuguese explorer to arrive in China was Jorge Alvares in 1513. Eventually, the explorers established a trading post in Hong Kong, beginning regular trade between Portugal and Southern China.
