Why Did Shays's Rebellion Enable Collective Action Among Elites of the Colonies

Why did Shays's rebellion enable collective action among elites of the colonies, ones who wanted to revise the Articles of Confederation?

A) It scared the country's remaining royal land and patent holders enough that they knew action had to be quickly taken.
B) The rebellion provided politicians who were already convinced of the Articles' inadequacy with the ammunition they needed to convince a broader public of the same.
C) The rebellion showed that the national government was now strong enough to quell an uprising, making the creation of a stronger central government a more attainable goal.
D) Shays introduced key figures in western Massachusetts to the concept of civil disobedience, which in turn caught on with opponents of the Articles across the country.
