Which of the following is NOT one of the three branches of government?

The correct answer is "D. Administrative" because the three branches of government, as established in the United States Constitution and practiced in Delaware, are the Legislative, Executive, and Judicial branches. These branches work together to govern and ensure a system of checks and balances.

The Legislative branch is responsible for creating laws, the Executive branch enforces those laws, and the Judicial branch interprets laws and resolves legal disputes. The term "Administrative" does not refer to a separate branch of government; rather, it describes activities and functions that may occur within the established branches, but it is not recognized as a distinct, foundational component of government structure. Thus, identifying "Administrative" highlights a misunderstanding of the constitutional framework and recognizes that it does not have the same standing as the other three branches.
