Since there are 16 people ahead of you and the ticket booth can process customers at a rate of 80 tickets per hour, it would take approximately 12 minutes for all 16 people to buy their tickets (80 tickets per hour / 60 minutes = 1.33 tickets per minute; 16 people / 1.33 tickets per minute = 12.03 minutes). Therefore, you can expect to wait in line for greater than 10 but less than or equal to 15 minutes. So the correct choice is C.
