Final answer:
Delegates met at the First Continental Congress to address grievances and coordinate a response to British policies, not to declare independence.
Step-by-step explanation:
The sentence that best explains why delegates met at the First Continental Congress is:
D) To address grievances and coordinate a response to British policies.
The delegates came together in a spirit of cooperation to formally address the Intolerable Acts by drafting a list of grievances and a declaration of the rights of the colonists.
They also created the Continental Association to enforce a boycott of British goods.
Though declaring independence was not the goal at that time, the assembly laid the groundwork for the colonies' eventual decision to seek independence.
