In its Declaration of Secession, South Carolina uses the Declaration of Independence to establish:

a) that South Carolina is an independent state, which is therefore free to secede from the Union if it so chooses

b) that South Carolina is an independent state, which can secede if other states ignore the ends for which the Constitution was adopted

c) that South Carolina is an independent state, which is free to secede if it understands the Constitution differently than other states do

d) that South Carolina was an independent state before it adopted the Constitution, and can become one again if the Constitution is violated

a) that South Carolina is an independent state, which is therefore free to secede from the Union if it so chooses
