Explanations:The question asks which Indian state has the least number of rivers. To understand this, we need to consider the geographical and climatic conditions of each state. Rivers are formed due to various factors such as rainfall, topography, and the presence of natural water sources like springs and glaciers.
Tamil Nadu, located in the southern part of India, has a significant number of rivers, including the Cauvery, which is one of the major rivers in southern India. The state's climate and topography support the formation of several rivers, making it unlikely to have the least number of rivers.
Jammu and Kashmir, located in the northern part of India, is known for its numerous rivers, including the Jhelum and Chenab, which are part of the Indus River system. The state's topography, with the presence of the Himalayas, supports the formation of many rivers, making it incorrect to consider it as having the least number of rivers.
Nagaland, located in the northeastern part of India, has a relatively small number of rivers compared to other states. This is due to its geographical and climatic conditions. Nagaland is characterized by hilly terrain and a tropical monsoon climate, which does not support the formation of a large river system. The state's rivers are generally small and seasonal, making it the correct answer for having the least number of rivers among the given options.
It is important to note that the number of rivers in a state is influenced by various factors, including the state's size, topography, and climate. Understanding these factors helps in determining the river distribution in different states. In this case, Nagaland's unique geographical and climatic conditions result in it having the least number of rivers among the given options.
