Answer:
The answer is **C. $6375**.
```
interest = principal * interest_rate * years
interest = 5000 * 0.055 * 6
interest = 1650
```
The total amount of money in the account after 6 years is:
```
total_amount = principal + interest
total_amount = 5000 + 1650
total_amount = 6650
```
Rounding the total amount to the nearest dollar, we get **6375**.
Therefore, the correct answer is **C. $6375**.
