The correct option is B Himachal Pradesh
States like Bihar, West Bengal, Uttar Pradesh, Haryana, Punjab, Kerala, and Tamil Nadu have high population densities. The areas with less than 250 persons per sq. km are low population density areas - such as Rajasthan, Himachal Pradesh, Uttaranchal, Chhattisgarh, Madhya Pradesh, Sikkim, Meghalaya, Manipur, Nagaland, and Arunachal Pradesh. The Union Territories of Jammu and Kashmir and Andaman and Nicobar Islands also fall in this category.
