Answer:
B. Interest groups.
Explanation:
Organizations of people who share common beliefs and try to influence government and public policy are best known as interest groups.
An interest group can be defined as a group of people sharing common aims, ideas and concerns, which seeks to influence government or a public policy.
The public action committee is an example of an interest group. In the United States of America, the public action committee was formed from the labor movement in July 1943 after the U.S. Congress prohibited unions from giving direct support and contributions to political candidates.
Hence, public action committees are created by interest groups primarily to influence elections by raising and distributing campaign funds to political candidates.
