Question

Which one of the following states has the lowest density of population?

• A. Nagaland
• B. Arunachal Pradesh
• C. Mizoram
• D. Himachal Pradesh

Hint:

A big area with a very small population gives the lowest density.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
Population density = population divided by area (persons per sq. km); north-eastern hill states generally have very low densities due to rugged terrain and small populations.

Step 2: Compare known densities (Census 2011, persons/sq.km):
Arunachal Pradesh \(\approx 17\); Mizoram \(\approx 52\); Himachal Pradesh \(\approx 123\); Nagaland \(\approx 119\).

Step 3: Pick the lowest:
Among these four, Arunachal Pradesh has by far the lowest density — it is in fact the least densely populated state in mainland India.

Step 4: Final Answer:
\[ \boxed{\text{Arunachal Pradesh}} \]
