The correct answer is A.
A political party is an organized group of people that share common view. They come together to hold power in the government. A political party that operates on a local level would deal with local issues first.
The need to improve local water facilities would be high on the party's agenda since it concerns people in the party's local jurisdiction. This issue would be discussed only on a local level since the problem is confined to a specific location. It is not an issue that would interest anybody on a national level.
The need for immigration reform, the reason to support a presidential and a congressional candidate are all issues that should be discussed at the state or federal level because they appeal to a broad audience. Immigration is a national affair and so is the election of the president. A congressional candidate election is state-bound so it would be discussed on the state level.
