The map shows the population density of India. The redder the area, the higher the concentration of the population. Which is the MOST likely reason for the high population density in the north eastern part of India?

One of the most likely reasons for the high population density in the northeastern part of India is the region's favorable geographical features and resources. The northeastern states of India are known for their fertile plains, abundant water sources, lush forests, and diverse flora and fauna. This region experiences heavy rainfall, which further promotes agricultural activities and supports a variety of crops. The favorable climate and availability of resources attract settlements and agricultural practices, resulting in a higher concentration of population in the area. Additionally, the region also shares borders with Bangladesh, Bhutan, Myanmar, and China, leading to cultural, economic, and trade influences, which might contribute to population density as well.
