The main problem with most conspiracy theories is that they fail the criterion of: a. simplicity.
b. acceptability.
c. scope.
d. plausibility.

The correct answer is B) acceptability.

The main problem with most conspiracy theories is that they fail the criterion of acceptability.

Conspiracy theories are not based on any solid scientific or historical background. That is why the scientific or academic world does not accept them as valid.

Theorists of the conspiracy based their points or views or opinions on oral stories, traditions, customs, and legends. And that is the problem. Many times, those factors cannot be evaluated through serious and valid research.

There are many subjects that fall in the category of conspiracies such as the existence of "Area 51," or Alien bases under the sea, the Illuminati that controls world economics, and many more.
