To find the percent rate of change, we need to calculate the daily growth rate first.

The population quadruples every day, which means it multiplies by 4. Therefore, the daily growth rate is 400% (or 4 times the original population).

To convert this to a percent rate of change, we subtract 100% from the growth rate and get:

400% - 100% = 300%

So the percent rate of change is 300%, which is equivalent to 138.63% rounded to 2 decimal places.

Therefore, the answer is B.
