PLEASE HELP, Thank you!

Bikes-for-Kids, Inc, designs, manufactures and sells bicycies for kids. While manufacturing a bicycle, a worker at the factory fails to properly attach a wheel to one of the bicycles. All the other bicycles produced at the factory are fine; they do not have this defect. This bicycle with the improperly attached wheel is sold to Davis Distributors, a wholesaler, which sells it to Trent's Sporting Goods, a sporting goods store, which sells the bike to Min, a customer. One day, while riding the bike, Min's daughter is injured because the wheel comes lose from the bicycle. The improperly attached wheel is an example of what kind of product defect?
