Answer:
A. The Declaration listed colonial complaints about many British policies.
Explanation:
"Throughout the 1760s and early 1770s, the North American colonists found themselves increasingly at odds with British imperial policies regarding taxation and frontier policy.
When repeated protests failed to influence British policies, and instead resulted in the closing of the port of Boston and the declaration of martial law in Massachusetts, the colonial governments sent delegates to a Continental Congress to coordinate a colonial boycott of British goods. [...]
By issuing the Declaration of Independence, adopted by the Continental Congress on July 4, 1776, the 13 American colonies severed their political connections to Great Britain. The Declaration summarized the colonists’ motivations for seeking independence."
