Correct option is D
The correct answer is (D) Bihar
Bihar has a high population density due to its large population and relatively small area, making it one of the most densely populated states in India.
The high density of Bihar has posed challenges in terms of infrastructure, healthcare, and education.
Bihar's agricultural productivity and rural economy also play a role in attracting a significant population in the region.
The state's urbanization is also growing, with the capital, Patna, being a major urban center in the region.
Despite its high population density, Bihar has made strides in improving its human development indicators in recent years.
West Bengal : West Bengal has a high population density but ranks lower than Bihar.
Kerala : Kerala has a moderate population density compared to Bihar and ranks second in terms of high literacy and human development but not the highest population density.
Uttar Pradesh : Uttar Pradesh is the most populous state, but its population density is lower than that of Bihar, though it has a significant contribution to India's overall population.
