You need to display the last names of those employees who have the letter "A" as the second character in their names. Which SQL statement displays the required results? （）

• A、SELECT last_name FROM EMP WHERE last_ name LIKE '_A%';
• B、SELECT last_name FROM EMP WHERE last name ='*A%'
• C、SELECT last_name FROM EMP WHERE last name ='_A%';
• D、SELECT last_name FROM EMP WHERE last name LIKE '*A%'
