A) This would be considered misuse if Trevor weighs more than most riders of mountain bikes.
B) This is a manufacturing defect, because the defect occurred in a manufactured product.
C) This is a design defect, because a sturdier design would not have failed.
D) This could be either a design or a manufacturing defect, and further information would be needed on the precise reason for the failure in order to determine which.
