Examine the data in the EMPLOYEES table:

Which statement will compute the total annual compensation for each employee?
Correct Answer: C
To calculate the total annual compensation, you need to sum the annual salary with the annual commission.
The annual commission is the monthly commission percentage times the monthly salary times 12 (months).
The NVL function is used to replace NULL with 0 for commission percentage when calculating the commission.
* A: This statement is incorrect because it does not handle NULL values for 'monthly_commission_pct', which will result in NULL for the entire expression if 'monthly_commission_pct' is NULL.
* B: This statement is syntactically incorrect because it lacks commas and proper parentheses to separate the column name 'last_ name' from the calculation.
* C: This is the correct statement as it uses NVL to replace NULL with 0 and calculates the total annual compensation correctly.
* D: This statement is incorrect because, like in option A, it does not handle NULL values in
'monthly_commission_pct', resulting in NULL if 'monthly_commission_pct' is NULL.
