Answer: Bill of Rights ratified
Step-by-step explanation:
Option A is incorrect because the slave trade was limited after the colonies received their independence due to some of the new states passing legislature against it.
Option B is equally wrong because the American colonies declared independence before Shay's rebellion.
Option C is wrong as well because the Boston Tea party was also before Shay's rebellion.
