Answer: c. inattentional blindness.
Explanation: Inattentional blindness occurs when we focus more on something that seems to demand more of our attention in a way that our perception is impaired that we can fail to see other obvious things at that moment.
This is a cause we are too focused to even notice these other aspects in our view.
It happens to almost all of us in most cases , eventhough you think you are concentrating on driving but you fail to notice when a car swerve on your lane.
When you are on the call you think you are still paying attention to the the road but since you are on the call which is taking all your attention you end up driving by, not noticing that the traffic light has turned red and you get a traffic light.
