The correct answer is C) conservatives may have different views on many issues.
The reason that there is no clear definition for a political conservative is that conservatives may have different views on many issues.
Although we can identify conservative people or parties, sometimes there is no clear definition of them because they have many different views, depending on the issue at hand. Generally speaking, a conservative person is one who is very traditional, he/she opposes to high taxes to finance social programs, they opposed labor unions, they do not like government regulation and have a patriotic sense.
