Your supervisor has asked you to remove a discontinued product from your company's inventory database. By doing this, it ensures that the inventory list remains current and prevents the sale of items no longer offered. What is the proper way to permanently delete this product from the database?
Apply a drop command to the product's table to remove the discontinued product.
Issue a delete command targeting the product's unique identifier to remove its record from the inventory table.
Use an update command to change the product's status to 'discontinued' in the inventory table.
Manually erase the product's information from the database management system interface.
