This query correctly retrieves the second-highest salary by first finding the maximum salary and then searching for the maximum salary that is less than the first maximum. The subquery (SELECT MAX(Salary) FROM Employee) retrieves the highest salary, and the main query finds the maximum salary that is smaller than that value, effectively returning the second-highest salary. This method ensures that the second-highest salary is retrieved by eliminating the highest salary and then finding the next largest value. Why Other Options Are Incorrect:
