Quizplus · Accepted Answer

All of the options are true. Using mobile phones in public places can create negative externalities for those around the user, as it may disturb the peace and quiet of the area. Additionally, the private costs of using a mobile phone do not reflect the costs imposed on others, as they may have to listen to the user's conversation or be distracted by the noise. Finally, phone conversations in public places can be annoying to bystanders, highlighting the need for bans or restrictions on their use in certain areas.
