Which phrase from the Preamble shows that the Constitution is meant to provide safety and protection measures for citizens? A.
form a more perfect Union
B.
provide for the common defence
C.
We the people of the United States
D.
establish this Constitution

Im pretty sure its B

Explanation:

the part i woulve put from the preamble tho would have been when it says "secure the blessings of liberty" but since thats not on here its going to have to be B since its obviously not C or D and A is only talking about creating a perfect union not about securing the blessings and providing daftey. B is saying it will provide for the common defense and the common defence is when like war will be called and so like its to protect the USA.
