The correct answer is (a) China.
China is the world’s leading producer of cotton textiles, accounting for 28% of global production in 2020. India is the second largest producer, accounting for 19% of global production. The United States is the third largest producer, accounting for 12% of global production. Russia is the fourth largest producer, accounting for 7% of global production.
China’s cotton textile industry is highly developed, with a large number of factories and mills. The industry is also very competitive, with many different companies producing a wide range of products. India’s cotton textile industry is also highly developed, but it is not as large as China’s industry. The United States’ cotton textile industry is smaller than both China’s and India’s industries. However, the United States’ industry is more technologically advanced than the industries in China and India. Russia’s cotton textile industry is the smallest of the four countries. The industry is not as developed as the industries in China, India, and the United States.
