The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The British policy of allowing the colonies to operate independently and not follow British laws was known as Salutary Neglect. The colonies were very successful since they could produce, buy, and sell goods without government control.
At the beginning of the 18th century, the government of Great Britain changed its political approach for the American colonies. After a series of Navigating Acts that had harmed the economy of the colonists, the English monarchy decided to diminish the enforcement of harsh laws and gave more freedom to trade. The only condition the monarchy asked for, was that American colonists remained loyal to the King of England.
So this was a time when colonists merchants could prosper.
