The correct answer is letter D) change blindness.
Explanation:
A study that is known as the "door study" was conducted by exposing someone to major visual changes. Participants would be regular people giving instructions to a man. While they talked, two other men walked between them carrying a door. The man who had asked for directions would be replaced by a different man, but the change would go unnoticed by the participants in approximately 50% of the times. That phenomenon is called change blindness, and it usually takes place when a person's attention is not focused on visual details.
