Answer:
Constitution, And United States needs to be capitalized.
Explanation:
United States is what I saw that needed to be capitalized. I thought 'the' might need to be capitalized but I believe not. Sorry if this is wrong.
I would say it is D Personification.
First of all, the word begins with a capital letter which gives entity to the concept. It would be considered in the same category of a proper name. It is like giving "Death" humanlike qualities or characteristic.
So what is your doubt in this?
