Liabilities Under a Contract Can Be Assigned (Transferred)from One Party

Liabilities under a contract can be assigned (transferred) from one party to another by 'novation'.This means that all the parties agree:

A) to replace the old contract with a new one that contains the same terms but allows a third party to be substituted for one of the original parties.
B) to enter into an additional contract and pay novo damages to one or more parties.
C) to replace the old contract with a new one that contains different terms.
D) to discharge (end) the original contract and try to find new business partners
