Answer:
d. Many power holders and many points of access to power.
Explanation:
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.
Pluralism, when it refers to interest groups, means many power holders and many points of access to power.
The points of access to power includes; charisma, skill, experience, money, knowledge, prestige, legal authority, free time etc.
Since the interest groups are usually made up of numerous people or groups of people, it simply means that there are many power holders and none among them is really all powerful.
<em>Generally, as the number of power holders increases so does the number of access to power. </em>
