The correct option is (A),

The population of the country can be found by looking at the value of the bar where the x-axis denotes the year and the y-axis represents the population in lakhs.

The population of the country in the year $2006$ is $220$ Lakhs.

The population of the country in the year $2007$ is $350$ Lakhs

Hence, the difference between the population in the years $2007$ and $2006$ is $350-220=130$ Lakhs.
