I would put the answer C.
The correct answer is C) the Burlingame Treaty.
The treaty that improved U.S. relations with China was the Burlingame Treaty.
The Burlingame-Seward Treaty of 1868 improved the conditions established on the Treaty of Tianjun of 1858. With the signing of the new Burlingame Treaty, the relationship between the United States and China improved. Immigration restrictions were modified and the US federal government diminished its intromission in Chinese affairs.
