Can someone please explain the right answer?

Hi Zia305, thanks for the question.

If K is one of the nominees, then K must be the mayor. This is because the treasurer position can only be filled by F or H, while K cannot be a councillor.

Knowing that K is now the mayor in this scenario, this triggers the contrapositive of the second rule. When J is not mayor, H is not councillor.

This is how we get answer choice C.
