How can this implementation be achieved?

Company XYZ runs OSPF in their network. A design engineer decides to implement hot-potato routing architecture.

How can this implementation be achieved?
A . Enable iBGP and apply prepend to ensure all prefixes will have the same length of the AS path attribute value.
B . Redistribute the external prefixes onto OSPF and ensure the total metric calculation includes only the ext value and the value is the same in all ASBRs.
C . Enable OSPF load-balancing over unequal cost path.
D . Redistribute the external prefixes onto OSPF and ensure that the total metric calculation includes external internal values.
