Answer:
b
Explanation:
The correct answer is **b. $19,661.94**.
To calculate the future value of an investment, we can use the following formula:
```
Future value = Present value * (1 + Interest rate)^Number of years
```
In this case, the present value is $15,000, the interest rate is 7%, and the number of years is 3.
```
Future value = $15,000 * (1 + 0.07)^3 = $19,661.94
```
Therefore, the future value of the investment after three years is $19,661.94.
