A major challenge faced by public transport systems in Karnataka:

Traffic congestion
Lack of infrastructure
Financial constraints
All of the above

The correct answer is D) All of the above.

Traffic congestion is a major problem in Karnataka, as it is in many other parts of India. The state’s capital, Bangalore, is notorious for its traffic jams, which can make it difficult and time-consuming to get around. This is due to a number of factors, including the city’s rapid population growth, the increasing number of vehicles on the road, and the lack of adequate infrastructure.

Lack of infrastructure is another major challenge faced by public transport systems in Karnataka. This includes the lack of adequate bus stations and terminals, as well as the poor condition of many roads and highways. This makes it difficult for people to use public transport, and can also lead to delays and cancellations.

Financial constraints are also a major challenge faced by public transport systems in Karnataka. The state government has been struggling to fund public transport in recent years, which has led to cuts in services and a decline in the quality of service. This has made it difficult for people to rely on public transport, and has led to an increase in the number of people using private vehicles.

All of these factors have contributed to the challenges faced by public transport systems in Karnataka. It is important to address these challenges in order to improve the quality of life for the people of the state.
