The answer is: in New England
The Connecticut River is the longest river in the region of New England. It runs along 643 km through four states: Connecticut, Massachusetts, Vermont, New Hampshire. It also spans small areas of Maine and the province of Quebec in Canada.
The rest of the choices are incorrect because the southern colonies were in the states of Maryland, Virginia, North and South Carolina, and Georgia; the Cumberland gap is a pass in the Appalachian Mountains; and the Ohio River is a tributary of the Mississippi through Pennsylvania, Ohio, West Virginia, Kentucky, Indiana and Illinois.
