The correct answer is option C, Jind.
According to the 2011 census, the population growth rate of Jind district was 12.4%, which is the lowest among all the districts of Haryana. The population growth rate of Ambala district was 15.8%, Jhajjar district was 16.3%, and Gurugram district was 21.9%.
There are a number of factors that could have contributed to the low population growth rate in Jind district. One possibility is that the district has a relatively high proportion of elderly people. According to the 2011 census, the proportion of people aged 60 and above in Jind district was 12.2%, which is higher than the state average of 9.5%. This suggests that the population growth rate in Jind district may be slowing down due to natural causes, such as a decline in the birth rate.
Another possibility is that the low population growth rate in Jind district is due to migration. According to the 2011 census, the net migration rate (the difference between the number of people moving into and out of a district) in Jind district was -1.2%. This suggests that more people are leaving Jind district than are moving in. The reasons for this migration are not clear, but it could be due to factors such as a lack of job opportunities or poor infrastructure.
Whatever the reasons, the low population growth rate in Jind district is likely to have a number of implications for the district. For example, it could lead to a shortage of workers and a decline in the tax base. It could also put a strain on social services, such as healthcare and education.
