It is the last one!
If this is an actual LSAT question (I assume it is since has a 28 there, please remove the content of the question since it is copyrighted.)
To negate this answer choice: "Mayor Drabble has no political debt that is both of longer standing than the one she owes to Lee and could as suitably be repaid by an appointment to be the new head of the arts commission. "
Look at what this is saying. It is quite interesting. The argument says that Drabble has a debt to Lee and that he wants a certain job. Drabble also always repays her political debts as soon as possible.
However, for the argument to conclude "she will almost certainly appoint Lee" isn't necessary for Drabble to not have a debt to someone else that is interested in that same job?!
Imagine the conflict!
Anyways, to negate this, think about what this is saying.
Mayor Drabble has no political debt that is both A & B.
To negate this concept, simply say that she does have a political debt that is both A&B.
The original answer choice statement could imply that she has a case of one of A and B, or none of A and B. The logical opposite of not both is both.
