Verified Answer :

I believe the answer is: C. Johnson believed that the Union was paramount and southern states should be represented.

Johnson believe that leaving the southern states people left unrepresented in the government would only ignite the anger that might lead to the second civil war. Because of this, he made it easy for them to re-enter union and provide the southern states with the opportunity to send their representative for the legislative process.
