C Correct answer
Explanation

Let initial visitors be 100. Feb: 100 * 0.85 = 85. March: 85 * 1.20 = 102. The change from 100 to 102 is a 2% increase.

AI explanation

Let the initial number of visitors in January be 3400. In February, a 15% decrease results in 3400 multiplied by 0.85, giving 2890 visitors. In March, a 20% increase results in 2890 multiplied by 1.20, giving 3468 visitors. The difference between March and January is 3468 minus 3400, which is 68, and calculating (68/3400) * 100 reveals a 2% increase.
