The collective term for the first ten amendments to the Constitution is the

A. Preamble.

B. Articles.

C. Bill of Rights.

D. Declaration of Independence.

The Declaration of Independence is another document - not the constitution. (so D is not the correct answer)

The whole constitution is divided into Articles, not only the first ten Amendments (so B is not the correct answer).

The correct answer is C. Bill of Rights - this is what the first ten Amendments are!
