The correct option is B Uttar Pradesh
Uttar Pradesh holds about 16.5% of India’s total population - that is, 199 million, as per the 2011 census data. Sikkim, India’s smallest state, has the lowest population of 0.6 million. Its area is just 7,096 square kilometres, whereas the area of Uttar Pradesh is 2,43,286 square kilometres - about 34 times larger than that of Sikkim. India’s biggest state, Rajasthan, holds only 5.5 % of the total population because a large percentage of it is a desert - the Thar Desert.
