Final answer:
The rate of return on this stock is 8.0%.
Step-by-step explanation:
To calculate the rate of return on a stock, we need to divide the annual dividend by the current stock price. In this case, the annual dividend is $2.50 and the current stock price is $31.25. So the rate of return is $2.50 / $31.25 = 0.08 or 8%. Therefore, the correct answer is 8.0%.
