Final answer:
Option b is not correct because the economy of Southeast Asia in the sixteenth century involved more than just the exportation of agricultural produce.
Step-by-step explanation:
The correct answer is b. The region exported nothing but agricultural produce. In the sixteenth century, the economy of Southeast Asia was characterized by expanding regional and interregional trade, which included the exportation of various goods, not just agricultural produce. Agriculture was indeed becoming commercialized, and while the royal courts were major consumers of luxury goods, there was also a growing commercial market for these goods. Additionally, although agriculture was the economic basis of society, commerce was beginning to affect daily life. Therefore, option b is not correct.
