The correct answer is: A. China

Buddhism was first propagated outside India in China. This happened during the reign of Emperor Ming of Han (58-75 CE), who sent an envoy to India to invite Buddhist missionaries to China. The first Buddhist missionaries to China were Kashyapa Matanga and Buddhabhadra, who arrived in 67 CE. They translated Buddhist texts into Chinese and established the first Buddhist monasteries in China.

Buddhism quickly spread throughout China and became one of the major religions of the country. It had a profound impact on Chinese culture, art, and philosophy.

The other options are incorrect because:

  • B. Cambodia was not a major center of Buddhism until the 6th century CE.
  • C. Thailand was not a major center of Buddhism until the 13th century CE.
  • D. Ceylon (Sri Lanka) was a major center of Buddhism, but Buddhism was not first propagated there from India.
