Answer: A. was a collective act of representatives from all the colonies.
The collective act of representatives from all colonies was the reason the declaration of independence reflected the idea of a social contract. The declaration of independence was written by Thomas Jefferson. The declaration involved the separation of 13 North American British colonies from the rule of Great Britain. These states agreed to separate from the rule of Great Britain and form a sovereign state which would later be called the United States of America. July 4th was the day the separation was officially agreed on and that day has been adopted as a national holiday in the US ever since.
