Which one among the following States of India has the lowest density of population?

Census 2011 data show Arunachal Pradesh has the lowest state-level population density at about 17 persons per sq. km, which is substantially lower than the other options [1]. Sikkim’s density was around 86 persons per sq. km [1], Meghalaya about 132 persons per sq. km [2], and Himachal Pradesh approximately 123 persons per sq. km [3]. Given these comparative figures, Arunachal Pradesh (option 3) is the least densely populated state among the four choices. The answer is based on official state-wise density figures from the 2011 census and related demographic summaries [3].
