As the Trade in "Foreign Mud" (Opium) Began, Heavily Armed

As the trade in "foreign mud" (opium) began, heavily armed ships would unload their cargo of opium on small, sparsely inhabited offshore islands, from which:

A) Chinese officials like Lin Zexu would seize and destroy the product before it could reach a domestic market
B) British gunboats could be loaded up with excess opium, for transport to Britain.
C) The product would be consumed in raucous parties and rarely reach the mainland.
D) Middlemen picked up the drug and made their rounds on the mainland.
