​

В. The United States has become more concerned about China's human rights abuses.

Explanation:

The United States has become increasing vocal about its criticism of China's human rights abuses much to the chagrin of the Chinese who feel that the U.S. are trying to meddle in their internal affairs.

Amongst the issues the U.S. are concerned about is China's treatment of its Muslim Uyghurs, a tribe of over 10 million in Western China and China's treatment of protesters in Hong Kong who are against the dictatorial policies of the Communist party.
