C Correct answer
Explanation

Population after 3 years = P * (1 + r/100)^n = 18522000 * (1.05)^3 = 18522000 * 1.157625 = 21441530.5.

AI explanation

Using the compound interest formula for population growth, Final Population = Initial Population * (1 + Rate/100)^n. Substitute the given values to get 18522000 * (1 + 0.05)^3, which is 18522000 * 1.157625. Multiplying these values gives the approximate population of 21441530 after 3 years.
