The correct answer is A. 819/sq. km.
Kerala is a state in India with a population of 33.4 million and a land area of 38,866 square kilometers. This gives it a population density of 819 people per square kilometer, which is the highest in India. The population density of Kerala is due to a number of factors, including its fertile land, its tropical climate, and its proximity to the Arabian Sea. The state’s population is also relatively young, with a median age of 27.5 years. This means that there are more people of working age in Kerala, which has helped to boost the state’s economy.
The high population density of Kerala has both positive and negative effects. On the positive side, it has led to a vibrant economy and a strong social safety net. Kerala has one of the highest literacy rates in India, and it also has a good healthcare system. However, the high population density has also led to problems such as overcrowding, pollution, and traffic congestion.
The government of Kerala is working to address the challenges posed by the state’s high population density. It is investing in infrastructure, such as roads and public transportation, to improve the quality of life for its citizens. It is also working to promote sustainable development, such as by encouraging people to use public transportation and to recycle.
