Question

a person acting for a special-interest group, who tries to impact the voting on legislation or the decisions of government administrators, is known as a
a lobbyist.
b influence peddler.
c political activist.
d political action committee liaison.

Explanation:

A lobbyist is specifically defined as an individual who acts on behalf of a special-interest group to influence legislative votes and government administrative decisions. The other terms do not match this precise definition: "influence peddler" has a negative, informal connotation and is not the standard term; a "political activist" acts more broadly for political change, not just for a special-interest group's legislative/regulatory goals; a "political action committee liaison" focuses on coordinating with PACs, not direct legislative influence.

Answer:

A. lobbyist.
