The correct answer is C. 733.
The population density of Haryana as per census 2011 is 733 persons per square kilometer. This means that there are 733 people living in every square kilometer of Haryana.
The population density of a place is the number of people living in a given area. It is calculated by dividing the total population of the place by the area of the place.
The population density of Haryana is higher than the national average of 382 persons per square kilometer. This is because Haryana is a relatively small state with a large population.
The high population density of Haryana has a number of implications. For example, it puts a strain on resources such as water and land. It also leads to problems such as pollution and traffic congestion.
The government of Haryana is taking steps to address the challenges posed by the high population density. For example, it is investing in infrastructure development and promoting sustainable development.
