C Correct answer
Explanation

Population growth formula: P = P0 * (1 + r/100)^n. P = 20000 * (1.12)^10 = 20000 * 3.105848 = 62116.96, which rounds to 62117.

AI explanation

Using the compound growth formula, the population after 10 years is 20,000 multiplied by (1 + 0.12) raised to the power of 10. This calculates as 20,000 multiplied by 3.1058, giving approximately 62,117. The result is 62,117.
