Solution

The correct option is D Between 5-10%
The increase in number of individuals in the particular time is termed as natality or birth rate. While individual dying over a time period is termed as mortality or death rate.
In the given example, mortality is 60
So, natality will be 60 + 60 = 120.
Number of individuals in population is 1000
So, natural growth rate = Death rate - Birth rate = 60
So, percentage of growth rate = 60/1000×100 = 6%
Thus, the correct answer is option D.
