Which of the following terms refers to regular payments made for work over a set period?

The term that refers to regular payments made for work over a set period is salary. A salary is a fixed amount of money that an employee receives, typically on a monthly or yearly basis, regardless of the number of hours worked. This structure provides employees with a stable income, making it easier for them to manage their finances.

Wages typically refer to payments made on an hourly basis, which can fluctuate depending on the number of hours worked in a given pay period. Commission is often associated with sales roles and is based on the performance of the employee, specifically the sales they make. Incentives usually refer to bonuses or additional payments that are rewarded for achieving certain targets or performance levels, rather than regular base pay.

Hence, when it comes to defining regular and stable compensation over a specified duration of time, salary is the appropriate term.
