The correct answer is B: Foreigners would bring gifts for the emperor.
Further Explanation:
The tribute system was used by the Chinese for foreigners to gain access to passage across their lands. The foreigners would send a delegate ahead of the travelers and give gifts to the Chinese Emperor that were very valuable from their home countries.
After the gifts were given, they could pass and be allowed to trade in China's market. The Emperor would then return a gift to the foreigners or a "bestowel" that was equal or more valuable than the original gift the foreigners had given to enter China.
