Explanations:
Jammu and Kashmir is the northernmost state of India, situated in the Himalayan region. It is a state with a diverse geography, including high mountains, valleys, and plains. The state's location and terrain significantly influence its population density. The population density of Jammu and Kashmir is approximately 50-100 people per square kilometer, which is relatively low compared to other Indian states. This low density is due to the state's rugged and mountainous terrain, which limits the amount of habitable land available for settlement.
The state of Jammu and Kashmir is composed of three distinct regions: Jammu, Kashmir, and Ladakh. Each region has its own unique characteristics and population distribution. The Kashmir Valley, which is the most densely populated part of the state, has a higher population density compared to the sparsely populated regions of Jammu and Ladakh. The overall population density of the state is an average that takes into account the varying densities of these regions.
It is important to note that the population density can vary within the state due to the diverse geography. The mountainous regions of Ladakh, for example, have a much lower population density compared to the more fertile and accessible areas of the Kashmir Valley. The state's total area is approximately 222,236 square kilometers, and the population is around 12.5 million, which results in the average population density of 50-100 people per square kilometer.
In contrast, other options provided in the question are incorrect. Srinagar, which is mentioned in Option B, is the summer capital of Jammu and Kashmir and cannot be considered a state. Arunachal Pradesh, mentioned in Option D, is located in the northeastern part of India and is not the northernmost state. The population density provided in Option C is too high for Jammu and Kashmir, as the state's rugged terrain limits the number of people who can live in a given area.
Understanding the geographical location and population density of Indian states is crucial for various competitive examinations and general knowledge. Jammu and Kashmir's unique position and characteristics make it an important state to study in the context of Indian geography.
