Answer: implemented
Explanation:I used a bit of deductive logic. Design would be something with parameters and or boundaries like designing a home. Programmed just didn’t seem to fit in because there is no room for creative thinking. Approved? By whom?, you design something to reach a goal and follow to a degree what you designed, maybe within the walls you can add a closet or with design classes they are designed for a purpose but there must be ideas within a design that come up. So implemented makes sense so you have a design that seems to fit and certainly can be implemented meaning it can be used for a purpose to teach or help.
