Option A is correct because it highlights that brain scans indicate that every part of the brain has an important role to play, and therefore it is implausible that we only use 10 percent of it. Option B is also correct because it is not practical for an organ to require so much energy while being used so infrequently. Option C is correct because it argues that from an evolutionary perspective, we would not have evolved such a complex organ as the brain if we only utilized a small fraction of it. Therefore, all of the options provide compelling evidence that we use more than 10 percent of our brain, making D the correct answer.
