A. Because the colonies had de facto independence, they revolted when Britain enforced taxes and regulations on them.
Explanation:
The American Revolutionary War was a war of independence of the United States of America that was fought between the 19th of April, 1775 and 3rd of September, 1783. The war started when the delegates from the thirteen (13) American colonies in Congress (First continental congress) revolted against the Great Britain over their lack of representation in the colonies and refusal to give consent to parliament's taxation such as Stamp Act and Townshend Acts.
Hence, Britain's policy of salutary neglect contributed to the Revolutionary War because the colonies had de facto independence, they revolted when Britain enforced taxes and regulations on them.
