The correct answer is: c) Lower than the national average.
Punjab’s population growth rate is 1.1%, which is lower than the national average of 1.2%. This means that Punjab’s population is growing at a slower rate than the national population.
There are a number of factors that could contribute to Punjab’s lower population growth rate. One possibility is that the state has a higher proportion of older people than the national average. Older people are less likely to have children than younger people, so this could lead to a lower population growth rate.
Another possibility is that Punjab has a higher rate of emigration than the national average. Emigration is the movement of people out of a country, and it can lead to a lower population growth rate.
Finally, it is also possible that Punjab has a lower birth rate than the national average. A lower birth rate would also lead to a lower population growth rate.
It is important to note that the population growth rate is just one measure of a state’s population. Other measures, such as the population density and the age structure of the population, can also be important.
