Answer: c. The backfire effect predicts that it will be very difficult to convince a conspiracy-minded person to abandon his or her conspiracy theory.
Step-by-step explanation:
The Backfire Effect posits that when some people believe something to be true but are either told that it is untrue or presented with evidence to prove its inaccuracy, they will believe that claim even more.
In the case of conspiracy theories, the backfire effect makes conspiracy theorists believe even more that the claim is true because they will feel the truth is being covered up. It is therefore very hard for them to abandon their conspiracy theory.
