Like many developed regions, Tamil Nadu faces the challenge of:

The correct answer is: d) All of the above.

Tamil Nadu is a state in India that has been experiencing rapid economic growth in recent years. However, like many developed regions, Tamil Nadu is also facing a number of challenges, including a declining workforce, an increasing dependency ratio, and rising healthcare costs.

The declining workforce is due to a number of factors, including an aging population and a low birth rate. This is a major challenge for Tamil Nadu, as it means that there are fewer people working to support the economy. The increasing dependency ratio is also a major challenge. This is the ratio of people who are not working (such as children and the elderly) to people who are working. As the population ages, the dependency ratio is expected to increase, which will put a strain on the economy.

Rising healthcare costs are another major challenge for Tamil Nadu. This is due to a number of factors, including an aging population, an increase in chronic diseases, and the rising cost of medical technology. Rising healthcare costs can put a strain on both individuals and the government.

These are just some of the challenges that Tamil Nadu is facing. It is important to address these challenges in order to ensure the continued economic growth of the state.
