Letter D: the start of free trade within China.  

The Treaty of Nanking or Nanjing was agreed and signed on August 29, 1842.  Formally called as the Treaty of Peace, Friendship and Commerce between Her Majesty the Queen of Great Britain and Ireland and the Emperor of China, the treaty ended the First Opium War and became one of China’s unfair treaties because Britain had no obligatory duties towards the treaty. It has also made Hong Kong a British colony.
