Which of the following concepts is not included in the preamble of the u. s. constitution? a. form a more perfect unionb. promote the general welfarec. secure the blessings of libertyd. build a domestic militia

The correct answer is D. The Preamble of the U.S. Constitution doesn't include the concept of building a domestic militia.

Explanation:

The Preamble of the Constitution of the United States is an introductory text to the constitutional text, which briefly states the main purposes of the sanction of the Constitution.

Literally, its text states:

"We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America".

As we can see, there is no mention of a domestic militia included in the Preamble.
