What were the groups established throughout the colonies to transmit revolutionary ideas called?

The correct answer is Committees of Correspondence. These groups were formed in the American colonies in the years leading up to the Revolutionary War to facilitate communication and coordinate responses to British policies. The Committees of Correspondence played a crucial role in spreading revolutionary ideas and rallying support among the colonies.

These committees allowed for the quick exchange of information regarding British actions, colonial grievances, and organizing resistance efforts. By sharing pamphlets, letters, and other forms of communication, they helped unify the colonies in their struggle for independence, making them essential to mobilizing public opinion and maintaining a collective revolutionary spirit.

The other options refer to different types of organizations or committees that were not primarily focused on communication and the transmission of ideas in the same way the Committees of Correspondence were.
