Final answer:
The First Continental Congress viewed an attack by the British on any colony as an attack on all colonies, leading to a united stance. Their purpose was not just to address individual grievances but also to create a collective declaration of rights.
Step-by-step explanation:
The question asks what the First Continental Congress stated about an attack by the British on the colonies. During the First Continental Congress, the representatives of the American colonies viewed an attack by British forces as more than just an assault on a single colony; they saw it as an attack on the collective rights and liberties established by the colonies. This view led to a sentiment of unity and common cause among the colonies against British aggression.
Therefore, the correct answer to the student's question is: A) An attack on all of the colonies.
The purpose of the First Continental Congress was to respond to the Intolerable Acts by drafting a list of grievances against the British government and to draft a Declaration of American Rights, which provided a unified colonial stance towards these transgressions. It was an important step towards intercolonial unity and eventual independence.
