Answer:
b. Southeast Asia . . . exported
Explanation:
About 70% of the Southeast Asian population (Myanmar - formerly named Burma, Thailand, Cambodia, Laos, Vietnam, Indonesia, Brunei, East Timor and Singapore) live in rural areas, showing a strong link to primary activities. Thus, the bases of the economy of the countries of this region are agriculture and extraction, which results in the insertion of half of the economically active population in the primary sector.
The subcontinent is also a major producer of tea, sugar cane and black pepper, including tin production (Malaysia) and wood and oil (Indonesia). Indonesia, by the way, is one of the members of OPEC (Organization of Petroleum Exporting Countries), which brings together the largest oil producers in the world.
