Final answer:
After the Seven Years' War, Britain erroneously decided to increase its military presence, notably in the American Colonies. This decision strained Britain's relationship with the colonies as they were expected to share in the financial burden, precipitating the American Revolution.
Step-by-step explanation:
After its victory in the Seven Years' War, Britain made the mistake of thinking that it should increase its military presence (option A). Britain, having accrued a significant debt after the war, felt the need to further secure its territories and maintain its global supremacy. This increased military presence, especially in the American colonies, strained the relationship between Britain and the colonies, as the colonists were expected to shoulder a part of the financial burden caused by the military expansion and protection efforts in the form of taxes. This eventually led to resentment among the colonists and was one of the factors leading to the American Revolution.
