Answer: A. It banned colonial assembly.
Step-by-step explanation:
The British government viewed the Colony of Massachusetts as a threat due to its continued defiance of British mandates and its seemingly leading role in the rebellion of the other colonies to British directives as well.
The last straw to the British was the Boston Tea Part after which Parliament passed the Massachusetts Government Act of 1774 which placed Massachusetts directly under the control of a Royal governor who had absolute powers and suspended the Colonial assembly in order to remove any illusion of self-governance the people had.
