B Correct answer
Explanation

Population after 4 years = 14000 * (1 + 10/100)^4 = 14000 * (1.1)^4 = 14000 * 1.4641 = 20497.4. Rounding to the nearest whole number gives 20497.

AI explanation

The population after 4 years is found using the compound interest formula: Final Population = Initial Population * (1 + Rate/100)^n. Substituting the values gives 14000 * (1 + 0.10)^4, which equals 14000 * 1.4641. Multiplying these values results in a population of 20497.
