Answer:
D. Great Zimbabwe
Explanation:
Chinese fleets under Zheng He crisscrossed the Indian Ocean during the early part of the 15th century. The missions were diplomatic rather than commercial, but many exchanges of gift and produces were made.
During the 16th and 17th century, Japanese ships also made forays into Indian Ocean trade through the Red Seal ship system
During the Muslim period, in which the Muslims had dominated the trade across the Indian Ocean, the Gujaratis were bringing spices from the Moluccas as well as silk from China, in exchange for manufactured items such as textiles, and then selling them to the Egyptians and Arabs.Calicut was the center of Indian pepper exports to the Red Sea and Europe at this time with Egyptian and Arab traders being particularly active.
In Madagascar, merchants and slave traders from the Middle East (Shirazi Persians, Omani Arabs, Arabized Jews, accompanied by Bantus from southeast Africa) and from Asia (Gujaratis, Malays, Javanese, Bugis) were sometimes integrated within the indigenous Malagasy clans. New waves of Austronesian migrants arrived in Madagascar at this time leaving behind a lasting cultural and genetic legacy.
The Portuguese under Vasco da Gama discovered a naval route to the Indian Ocean through the southern tip of Africa in 1497–98. Initially, the Portuguese were mainly active in Calicut, but the northern region of Gujarat was even more important for trade, and an essential intermediary in east–west trade.
During the 16th century the Portuguese had established bases in the Persian Gulf. In 1602, the Iranian army under the command of Imam-Quli Khan Undiladze managed to expel the Portuguese from Bahrain. In 1622, with the help of four English ships, Abbas retook Hormuz from the Portuguese in the capture of Ormuz. He replaced it as a trading centre with a new port, Bandar Abbas, nearby on the mainland, but it never became as successful.
