The correct answer is: a) Major cities.
Traffic congestion is a major challenge faced in major cities. This is because major cities have a large population and a high number of vehicles. This can lead to traffic jams, which can cause delays and frustration for drivers.
National highways are also prone to traffic congestion, but this is usually not as severe as in major cities. This is because national highways are typically wider and have more lanes than roads in major cities.
Rural areas and tourist destinations are less likely to experience traffic congestion. This is because rural areas have a lower population and a lower number of vehicles. Tourist destinations may experience traffic congestion during peak tourist season, but this is usually not as severe as in major cities.
