Answer:
A. Supposed to maintain order and enforce customs regulations.
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.
The British were convinced that they needed to sent troops to Boston in order to help maintain order and enforce customs regulations due to the actions of the colonists with respect to the Townshend Acts. Consequently, on the 28th of September, 1768 the Secretary of State for the Colonies, Lord Hillsborough sent 2 regiments (4000 troops) to Boston.
Hence, British troops sent to Boston in 1768 were supposed to maintain order and enforce customs regulations.
