The correct answer is (a) 189.
The population density of Uttarakhand State was 189 persons per square kilometer as per the Census of India, 2011. This means that there were 189 people living in every square kilometer of the state.
The population density of a state is calculated by dividing the total population of the state by the total area of the state. The population density of Uttarakhand State is higher than the national average of 382 persons per square kilometer. This is because Uttarakhand State is a mountainous state with a relatively small area. The population of Uttarakhand State is concentrated in the plains, while the mountainous areas are sparsely populated.
The high population density of Uttarakhand State has a number of implications. One implication is that the state has a high demand for resources such as water, land, and energy. Another implication is that the state has a high level of pollution. The high population density also puts a strain on the infrastructure of the state, such as the roads, hospitals, and schools.
The government of Uttarakhand State is taking a number of measures to address the challenges posed by the high population density. One measure is to promote the development of industries in the state. This will create jobs and help to reduce the pressure on the agricultural sector. Another measure is to improve the infrastructure of the state. This will help to improve the quality of life of the people of the state.
