B) The 'quality function' curve
C) The 'S' curve
D) The 'J' curve

The 'bathtub' curve is commonly used to describe the failure probability of physical parts in operations. It shows a high initial failure rate, followed by a period of low failure rates, and then a high failure rate again as the part wears out. This shape resembles a bathtub, hence the name.
