The correct answer is: Both I and II follow.
The statement says that there was a tremendous response for the new XYZ’s car-booking with long queues of people complaining about the duration of business hours and arrangements. This means that the current arrangements are not sufficient to meet the demand.
Course of action I suggests that people should make their own arrangements for lunch and snacks and be ready to spend several hours. This is a temporary solution that will help people to cope with the current situation. However, it does not address the root cause of the problem, which is the lack of sufficient arrangements by the car dealer.
Course of action II suggests that the car dealer should make arrangements for more booking desks and increased business hours. This is a more permanent solution that will address the root cause of the problem. It will allow the car dealer to serve more people in less time, which will reduce the waiting time and improve customer satisfaction.
Therefore, both course of action I and II follow.
