B Correct answer
Explanation

The population after 2 years is calculated using the compound interest formula: P = 125000 * (1 + 8/100)^2 = 125000 * (1.08)^2 = 125000 * 1.1664 = 145800.

AI explanation

Applying the compound population growth formula, the future population equals the present population multiplied by (1 + r) to the power of n. The new population is 125,000 multiplied by 1.08, and then by 1.08 again, which equals 145,800.
