Solve for the difference between the price of the stocks at the beginning of the day and at the end. 

                                     d = $4.05 - $3.72 = $0.33

Divide this value by the original value of the stocks and multiply by 100% to get the rate of change.

                      ($0.33 / $3.72) x 100% = 8.87%

Thus, the answer is letter A. 8.9%.
