Answer:
The correct answer is letter "D": automatic replenishment.
Step-by-step explanation:
Replenishment refers to the restocking of a product according to customer demand. This practice aims to avoid overstocking. An automatic replenishment system is one where replenishment is done by computer software based on the inventory level of an institution and its sales orders. The software fastens the replenishment process instead of having an individual conducting that task.
