Answer:
The Middle East colonies were unique because they were Proprietary colonies, So, the correct option is a) Proprietary colonies.
Step-by-step explanation:
The Middle colonies, also known as the "breadbasket" colonies, were a group of English colonies in North America during the 17th and 18th centuries.
The Middle colonies included Pennsylvania, New York, New Jersey, and Delaware. What made these colonies unique was their governance structure.
The Middle colonies were proprietary colonies, meaning that the land and governing rights were granted to individuals or groups by the English monarch.
In the case of Pennsylvania, for example, it was founded by William Penn as a proprietary colony.
This arrangement gave the proprietors a considerable degree of control over the colony's government, allowing them to set up their own political and social systems.
Therefore, the correct answer is that the Middle colonies were proprietary colonies (option a).
