The correct answer is: A) There was an increase in jobs in China, but a decrease in job opportunities in the U.S.
The trade agreement between the U.S. and China, particularly around the time of China's accession to the World Trade Organization (WTO) in 2001, is often cited for its role in increasing job opportunities in China while simultaneously leading to concerns about job losses and manufacturing decline in certain sectors in the U.S. Consequently, many American jobs were outsourced to China due to cheaper labor costs.
