The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The British believed they would have greater success fighting the Americans in the South than they did in New England and the Middle Colonies because with the alliance signed with France, the French became formal allies to the Continental Army and the 13 colonies.
So the British Army decided to change its strategy and focused its effort in the loyalists, who were still loyal to the English crown. The Patriots supported independence, but the loyalists kept their support to the government of Britain. The British considered that most loyalists were located in the south of the North American territory. The British troops also wanted to enlist black slaves under the promise of liberty in the case England won the war.
This phase of the Revolutionary War was known as the Southern Phase of the American Revolutionary War (1778-1781).
