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

Hey there!

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

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.

Hope this helps!

Ithink it would be choices a and b. hope this !
