The correct answer is the ability to ignore or dismiss negative, intrusive thoughts.
People who don't have OCD have this ability, whereas people who are suffering from this disorder don't. They are unable to stop thinking negatively, they cannot stop doing the same action over and over again, which is one of the characteristics that distinguishes them from those who aren't suffering from OCD.
