B Correct answer
Explanation

Natural growth rate = (Birth rate - Death rate) / Population * 100 = (100 - 10) / 1000 * 100 = 90 / 1000 * 100 = 9%.

AI explanation

The percentage of natural growth rate is calculated by subtracting the death rate from the birth rate. Using the given numbers, the natural growth rate equals 100 minus 10, which gives a raw growth value of 90. Dividing this by the total population of 1000 and multiplying by 100 yields (90 / 1000) * 100, resulting in an exact natural growth rate of 9.0 percent.
