Which action is most likely to be taken by local political party rather than state or national party

Endorsing a presidential candidate is more likely to be done by a national party than a local party.

Explanation:

This is because when it's local, it's usually in support of local elected officials. It has nothing to do with national officials. However, when it is a national party, they could endorse a presidential candidate because that is ultimately more important and affects all people - hence the national. This is because whoever is chosen in such an important election changes the future of a country, and is something national organizations should deal with - not local ones.
