The middle colonies were next to which three great bays?

 The correct answer is -  Hudson, Delaware, Chesapeake.

Explanation:

The Middle colonies did not long coastline, and they were squeezed in between the Southern colonies and the New England colonies. Despite that, they still had a nice location as the part they had on the coastline was at an excellent position, and also some of the other great bays were located very close to their territory. The close proximity of the great bays like Hudson Bay, Delaware Bay, and Chesapeake Bay contributed to a free flowing large scale trade between the Middle colonies and Europe, and that made them wealthy and in a very good economic shape.
