The following are all types of compensation except: Salary ) Bonus Commission Promotion

The correct answer is: Promotion.<br /><br />Explanation: Salary, bonus, and commission are all forms of financial compensation that employees receive for their work. A promotion, on the other hand, is an advancement in an employee's rank or position within an organization, which may come with an increase in salary or additional responsibilities, but it is not a direct form of compensation itself.
