Answer:
Buddhism developed a much wider following among the Chinese people.
Step-by-step explanation:
The Han Dynasty fell in 220 CE and the Sui Dynasty emerged around 581 CE. These two dynasties may be successive but there is a huge gap of three decades in between the two.
For the three decades that remained 'silent' after the fall of the Han and the rise of the Sui Dynasty, the Buddhist religion would develop a much wider following among the Chinese people. This would begin the spread of Buddhism in the nation.
Thus, the correct answer is the second option.
