An interest group that focuses on policy benefits for senior citizens would be an example of a(n)

Question

a. philosophical interest group.
b. ideological group.
c. professional group.
d. business group.
e. single issue group.

Is it B? If no why

Answer 1

I don't think it's b. An ideological group would be a group that bases its activities on charity, religion, or a special philosophy.

The group that focuses on policy benefits for senior citizens has only one main goal. All of its activities are focused on improving insurance benefits for a specific age group.

Answer 2

According to my book, it would be D then. Is that correct?

Answer 3

I suppose it could be D. But I think "single issue group" defines it better.
